The pch creation so far used signal and slots but there was no explicit
pipeline. This patch is introducing the same architecture like the
refactoring plugin. It is filtering out older project parts from the
pipeline.

So far we only compiled the precompiled headers only sequentially. The
process generator is creating, managing a queue of processes to compile
the PCHs parallel.

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.
