Get rid of an else branch to simplify code layout. No functional changes at all.
==============
This series is an attempt to reduce the control structure depth of the code
base, maintaining at the same time its exact same behaviour, bugs included. It
is, in a sense, an initial attempt at a refactoring in the spirit of its
original definition [0].
The idea beyond this refactoring is that reducing the code depth and, sometimes,
inverting some conditions, bugs and logic errors may become easier to spot, and
the code easier to read.
When looked at ignoring whitespace changes, all of these diffs should appear
trivial.

It's just synctactic sugar, but it is always better than executing string
concatenations in one's mind.
Do not do this with files in src/static, because we want to keep IE 11
compatibility.
The old "static/custom" directory is replaced by "static/skins/<skinName>",
where <skinName> is taken from settings.json.
When no value is found, a default of "no-skin" is assumed, so that backward
compatibility is maintained.
The most evident security concerns have been addressed.
Closes#3471.
skinName must be a single string (no directory separators in it) pointing to an
existing directory under /src/static/skins.
In case these conditions are not met, its value is rewritten to "no-skin".
Also, the value of skinName if sent to the client via clientVars for allowing
its use it in the browser.
Currently, an Etherpad skin requires the existence of 6 files:
- index.{css,js}
- pad.{css,js}
- timeslider.{css,js}
In the default empty skin (in static/custom), there were 2 small placeholders
({js,css}.template) to be copied in place by the startup script in case no skin
was in use.
Now that we are moving to multiple directories (see #3471) we can simply commit
the example files and remove the copying code from the startup script.
Not performing encoding/decoding when traversing logical domains is a security
risk.
String concatenation is not great, too, but this change is just focused on
allowing the implementation of skin support.
If you edit `src/templates/export_html.html` to remove the
`<meta name="changedby" content="Etherpad">` tag[1], PDF export with
soffice has a bug: the first word of the pad is deleted and a blank page
is inserted as first page (the pad's text begins on the second page).
The `--writer` soffice option avoids that bug.
[1] you may want to delete that tag since it is inserted as a comment in
.doc or .odt soffice export.
It is better to keep the dirtyDB settings together, so they can be commented out
via a /* ... */.
Nested comments blocks would crash the application on start, because they are
syntactically incorrect.
Let's reduce this possibility, promoting an easier standard.
This file uses it for robots.txt and favicon.ico.
This makes use of the new stable settings.root introduced with #3466, and will
be modified when introducing support for custom skins.
This should look to consistent locations when looking for relative paths,
without depending on current working directory.
For absolute paths, nothing changes.
This is just a function (with an ugly side effect for caching purposes) that
heuristically tries to compute the Etherpad installation path when running under
Unix and win32 (they have different file system layouts).
This path can be used by Etherpad as a base for all the relative paths, in order
to be deterministic and not depending on cwd.
This is the location that is choosen by default when Etherpad starts with no
settings.json file.
It was different than the one contained into setting.json.template.
Version 2.x is not backwards compatible with 1.x.
However, according to [0], [1] and [2], it seems that the biggest concern is
when mixing different server and client versions, and this is not Etherpad's
case.
Smoke tested (successfully) on Firefox 61, Chromium 68.

Written the changelog and updated package.json.
From now on, releases will be cut from develop, and merged directly into master.
Each release will be a tag on the master branch (e.g. 1.7.0).
A "release/1.7.0" branch will eventually be created only if/when a hotfix will
be needed.
Starting with Etherpad 1.7.0, the branching strategies for releases will be
simplified.
Leaving this script here, as it's useful for documenting other release-related
activities.
