Editor: Move LastBuildConfiguration to user data configuration file

Moved LastBuildConfiguration to a new class to house workspace settings
(potentially things like which windows were open). Editor ignores
workspace settings if the section isn't found. Bumped the user data
format version to 3.4.0.1.
Debian: Ignore that agslua is not in the source traball, because it's a git submodule.
ags+libraries: add hint about updating chroots.
Common: removed padding buffer from AlignedStream class
