Adds a parser option to upload a link to TokyoTosho that's already been
uploaded to nyaa, and crashes out hard if you use it. It does nothing.
Edit .link.txt formatting

Output file now gets the same tosho link as verbose. Also it gets the
view URL for funsies, because copy/paste is slightly easier that
copy/paste/edit even though it's only one word.
Does some of what the branch name says

Also fixes a bug introduced possibly between commits.

I really need to commit more often when making sweeping changes like
this.

Or, you know, at least before waiting three months.
Fix Stupidity

So, that previous commit actually included everything for the feature...
except it called the wrong variable name. In fact, it called a variable
that didn't get populated to open as a file, accomplishing nothing.

By switching it to link_data_filename, which is y'know the string that
link_log writes to, it works. Thanks for backing up your submissions
long enough for me to test this feature, tosho!
Help Update

Reworded the --up-tosho description, and fixed a spacing error on -l.
Merge branch 'ToshoPreviouslyUploaded' into develop

Adds a long flag that will read the link.txt file from a previously
uploaded (but not tosho linked) video, and submits the download link to
tokyotosho. Just in case you need to do them separately for some reason.
