missed a rebase for one test
adding PCH generation to plex

Instead of mixing the plx code with the user code. Quite busted atm but
it does generate something into the stdafx.h file but ODR is preventing
it from linking of course.
checkpoint on PCH generation for plex

As of this, plex.exe is broken, it can be made to work back if
ProcessEntities2 is not executed.
EOL change
second checkpoint on PCH generation for plex

Can detect some freestanding functions now.
PCH checkpoint #3

Catalog fixes, so plex.exe can do its job.
PCH checkpoint #4

1- Better detect the enclosing namespace
2- Detect fwd declaration vs definition.

At this point it seems to do a reasonable job at detecting all the
signatures that need to be split according to the current linker errors.
PCH checkpoint #5

Things are kind of broken now but my PC keeps BSODing so better to
commit.
