QFileWatcher is only reporting one path per signal which is suboptimal if
you change many files at once. This patch is introducing a timer which is
waiting some time time to see if more path changes are reported and is
collecting them in a vector.

Compiling every header file again and again is quite time comsuming. There
are technics to improve this like preambles(a kind of automated
precompiled header) but they don't share their data between translation
units. This approach provides an automatically generated precompiled
header for every project and subproject to improve the loading time.
