Craftbench portable mode

While this file sits next to craftbench.exe, Craftbench keeps its settings, its
download cache and its record of installed apps in the CraftbenchData folder beside it, and
writes nothing to %APPDATA%. Copy the whole folder to move Craftbench with its settings.

Delete this file to use the normal per-user settings folder (%APPDATA%\Craftbench) instead.
If CraftbenchData can't be written (for example on a read-only drive), Craftbench says
so and uses %APPDATA%\Craftbench instead.
