* added: class HTMLFilter

files: htmlfilter.h htmlfilter.cpp
         this is an html filter used to make the html output looking better
         this is a very lightweight filter
         (without using any dynamic memory - some memory is allocated only at the beginning - in ctors)
         this filter has O(n) complexity over the whole html string
* added: antyspamming method
         if the POST request is sent too fast after the GET
         it is treated as a spam
         only for no logged users and only in 'emacs' and 'createthread' functions
