version 0.1 - last minute release

The changes since v0.1-rc4 are piling up and moving so far away from what v0.1-rc1 was like, so here's a quick v0.1 release. The next release will be v0.2 (or rather v0.2-rc1), which will feature the new type system and will be more useful.

Changes since rc4

• add wxLua copilot GUI (8b9d1ac)
• allow importing other alive scripts (22fa7e3, 4b2410d, f1eb271, 7b3f0e8)
• lots of fixes
