Ivan Sorokin de5f38a160 Speedup compilation speed 
libtorrent has a relatively heavy headers, that take lots of time to
process. This commit removes unnecessary includes of libtorrent headers
and replaces them with forward declarations.

I had to move some functions in QBtSession from slots to regular
functions because moc'ed file want to see complete types of all
parameters of slots.

"time make" of full rebuild before this series of commits:
