Remove legacy stuff

[splhack]

No one maintains MacVim_legacy.xcodeproj and PSMTabBarControl_legacy.xcodeproj. It seems no one builds MacVim on OS X 10.6 or earlier. So we can remove these and also 10.4, 10.5 and 10.6 stuff from the code, for example, MMAtsuiTextView.m.

I'll create macvim-dev/macvim-tiger or whatever if anyone wants to maintain MacVim for 10.4, 10.5 and 10.6. Please let me know.

Just don't remove the non-native fullscreen mode. It really has nothing to do with Tiger/Leopard/Snow, except indirectly. (It is the only kind of fullscreen mode that can be used on Tiger/Leopard/Snow). It works beautifully on all newer OS versions. It is also superior to native fullscreen mode in almost every respect.

I know and will fix #7.

For MacPorts, we received one report of build errors on OS X 10.6. At least there still seem to be users around, but it does not even build in the current snapshot release.

I'll merge #178 soon anyway. I'll create macvim-dev/macvim-tiger or whatever if anyone wants to maintain MacVim for 10.4, 10.5 and 10.6. Please let me know.

Hi, 10.6 user here (the last snapshot build I can compile as-is is 80). I found this thread while trying to restore 10.6 support to a more recent build; there are probably plenty more qualified people to be maintainers of a legacy branch but I'd like to help.

[splhack]

@rhendric the first thing, could you create a pull request for updating MacVim_legacy.xcodeproj and PSMTabBarControl_legacy.xcodeproj? I don't merge #178 if you maintain pre-10.7 code actively in the master branch.

Are the legacy xcodeprojs for 10.6? My reading is that they're only for 10.4 and 10.5, which I can't test.

A 10.6 build based on snapshot 88 appears very achievable with a minimum of edits/conditionals, by the way. The biggest issue is the new qlstephen subproject, which I just dropped altogether. If MacVim_legacy.xcodeproj becomes for 10.6 instead of for 10.4 and 10.5, then that's easily addressed; otherwise, it's the only change I'm not sure how to package up for a PR.

No one wants to maintain 10.4 and 10.5. I'll remove 10.4 and 10.5 stuff and _legacy.xcodeproj.
