Hardening/style guide palib

### Description
Removed around 3300 style-guide errors from palib.
I have left 8 errors as they are especially hard to remove.
Also, a few modifications in my intents to compile under Ubuntu 14.04 are seen in CMakeLists.txt.
I prefer to save these modifications (they only affect Ubuntu 14.04).

About a FIXME, rest assured this will not be forgotten.
However, what we will probably do is to just skip Ubuntu 14.04 and stick to linux versions with libboost 1.49 or 1.53 installed by default.

But sure, I can add a FIXME for this
