Please backport lgeneral 1.2.3 (universe) from raring

Please backport lgeneral 1.2.3-1 (universe) from raring to precise.

Reason for the backport:
========================
The 1.2.x series offers a number of benefits over precise's 1.1.1: More aggressive and smarter AI, rule changes for level bombers to make them more useful, various (debuf) corrections to artillery to make them less overpowered, and tons and tons of bugfixes. A full listing of changes will be attached.

Testing:
========
Mark off items in the checklist [X] as you test them, but please leave the checklist so that backporters can quickly evaluate the state of testing.

You can test-build the backport in your PPA with backportpackage:
$ backportpackage -u ppa:<lp username>/<ppa name> -s raring -d precise task
$ backportpackage -u ppa:<lp username>/<ppa name> -s raring -d quantal task

* precise:
[X] Package builds without modification
[X] lgeneral installs cleanly and runs

* quantal:
[X] Package builds without modification
[X] lgeneral installs cleanly and runs

I've played several scenarios with lgeneral 1.2.3 on precise and one scenario with it on quantal, after having played 1.1.1 a lot. The changes to artillery and level bombers are quite noticeable (and affect my personal strategy), but in a good way - previously level bombers were totally useless, and artillery + tactical bombers would ensure victory. With 1.2.3, it's not nearly as trivially easy.

Note that the campaign scenarios are (as usual) available from http://sourceforge.net/projects/lgeneral/?source=dlp. (Obviously, the game isn't playable without at least one scenario installed.) The README explains how to install them.
