Upgrade mktorrent from the precompiled 1.0.4 in apt-get to custom built 1.1 due to the requirements of the -s flag on select sites.
This allows a Source field to be generated in the torrent which is required for sites like PasstheHeadphones to allow cross-seeding
Also if PTHBetter is installed allows to fix a error in regards to 1.0.4 not having the source field.
