Incoming FOIA Portal Task Communication Link Handling broken

[morisy]

So there's some weird Markdown related (I think) bug with incoming portal tasks, where the incoming link is pseudo markdown:

Which isn't that bad except then the actual hyper link points to '''
'''
http://E4d5132a685bea183861f69cf4fcc10f887fa3a7e_Q21916_D1949800.pdf](https://efoia.fbi.gov/download-file/submission-4d5132a685bea183861f69cf4fcc10f887fa3a7e/NjtLkIbq6THAuXk/E4d5132a685bea183861f69cf4fcc10f887fa3a7e_Q21916_D1949800.pdf)"
'''
which is a bad link which makes completing the task more complicated.

So the problem is on all communications, not just portal tasks. The Django urlize template filter does not handle these links correctly due to the way they are formatted. I tried replacing them with bleach.linkify, which processes them correctly, but turned out to be unbearably slow. Will try to come up with a reasonable solution.
