ui-tree: add support for source-filter option

Browse Source 
This new option is used to specify an external command which will be
executed when displaying blob content in the tree view. Blob content
will be written to STDIN of the filter and STDOUT from the filter
will be included verbatim in the html output from cgit. The file name
of the blob will be passed as the only argument to the filter command.

source-filter::

this can be used to implement e.g. syntax highlighting. Default value:
none.
