hard-coded path to lua headers

[Per]

In lua/lua/Lua.h (and possibly other files), include paths to lua headers have a hard-coded path that includes a version number. This may not be correct for some installations, and breaks badly on Fedora 8, for instance. The includes should not include a path element, and the path should instead be discovered and added as an include path by cmake.

From talking to you on irc -- Fedora using /usr/include/lua.h and not /usr/include/lua-5.1/lua.h -- makes it hard to co-install. I added quirks for it. (1106) A better solution might require cmake script patches. ^^

New Lua macros were made for CMakeList.txt and source files that were affected to search for more naming conventions of the library/path/include files. This should close the bug.
