Support multiple inputs per compile line again
Fix bug introduced by previous commit.
Don't crash when clearing projects while restoring
Support multiple unresolvedInputLocationss
Bump rct.
Only support known compilers. E.g. if the compiler doesn't look like a
variant of gcc/g++/clang/clang++ it has to be specified in -U or in
rdmrc for it to work.
Use weak ptr to synchronize rather than path. Otherwise the project
could be "resurrected".
Try to avoid compile warnings.
Fix issue #173. Remove some code that was needed back before rtags was
based on line and column.
