v0.5.0: More attacker options & respect Towny's per-world war restrictions

Hello, again!

Well... It has been a busy couple of months here, so I do apologize for not making an earlier release.

For developers, this marks the first release with working Jitpack support, since at least https://github.com/TownyAdvanced/FlagWar/releases/tag/0.2.0-devel. So, depend away!

For administrators, you will need to run Towny 0.97.2.0, or later. Support for earlier versions has been dropped. Also, a bit of a warning to early-adopters: This release is severely lacking in the testing department.

Please report any regressions ASAP so that they can be taken care of.
