Highlighting of text parts and source codes

This adds 'Format as' submenu to the preview pane context menu.
The submenu is available only for text/plain parts or parts
with a source code (we support about 40 various types). Using
the 'highlight' utility, the formatter processes the part and
highlights the source code it contains.
