Search and replace buffers are now passed from the GUI to the Model

Browse Source 
just by their file-name, and directly accessed there.
All string/latex exporting of those buffers is handled on the Model
side (lyxfind.cpp) according to the selected options.
Fixed bugs when searching with ignore-format disabled material
in the middle of a paragraph, and when using regular expressions.
