Common code for retrieving translations and GSettings schemas has
been factored out into lib/convenience.js, which is part of
every extension installation.
Since that code relies on renames done at zip file creation time,
extensions can no longer be installed with "make install". Instead,
one should create the zip file and install it with the tweak-tool.
There is also a bash script, local-install.sh, that will install
everything in zip-files.
Also, since the GSettingsSchemaSource code is not yet in a stable
GLib release, extensions using GSettings have seen their stable
shell version removed.
If a theme cannot be found in the user directory, try in system
data dirs (XDG_DATA_DIRS, usually /usr/share and /usr/local/share)

Previously null stylesheets were ignored, making it impossible to
reset the default. We still need to filter out invalid (non existing)
stylesheets, as no check is performed by shell code.
