#12 Merge in improvements from pugg mainline

[Alex]

From pugg.sourceforge.net

Release Notes
0.5 :

This version is an attemp to get back to Pugg development. Thus I replaced most of the code >from the previous version with the version I use in my own projects. I omitted C++11 code
(mostly auto and unique_ptr) in order not to break old compilers.

Wstring support is removed as it complicates the code a and I don't think it is used by anyone
(If I'm wrong mail me and I will add it back).

Name convension changes break old code but it won't be very hard to replace old code.

History
0.5

New Documentation
Changed to Boost license for more freedom.
Name convension changes
wstring support is removed
Server class is in Kernel.h and is used from Kernel class.
Changed to mercurial

I don't thing we will remove wstring support (just rewrite it completely), but we should have a look & merge other stuff in.

Note about wstring: support in 0.8 (next 1.0 prelim) will be removed temporarily.
