From ACE to Boost (lets boost CMaNGOS)

ACE was used from a long time but we decided to use Boost instead.
Most modern lib and c++11 compliant.

I consider this as initial commit. So i choosed to squash all 35+ commit
into one.
We'll list here main authors of this commit.

@Ambal
@Vladimir
@Havoc
@Schmoozerd
@Cyberium

Some others also have been involved to made this possible i unfortunaly
don't have all involved name. Special thanks to @qvipka (who convainced
me to work on it by its motivation and compil fixes)

Sure its not finished especialy network part need some rework at my point
of view.
Also backtrace now not work so we need a new way to implement it.
Finaly lot of feedback will be needed to make it pushable to master so we
count on you for that part.
Delete ACE from repository
Delete older VS file (may be will reinsert them before make it to master)
And delete ace related stuff in project file
