tabassassin created a mess and I failed to resolve it properly.
Attempt #2. See #2301.
FixRM #8396 change all lib use of regex to 8-bit pattern
Bump requirement for packetfu

Not sure why this version is pinned, I'm pretty trustworthy.

I would love to see @jlee-r7 or @hdm-r7 land this, since they were the
ones who so a problem with binary regexes in 1.1.8
Gemfile.lock, too
Fix description
Update information about original discovery

Update info about original discovoery. See #2337 too.
Land #2363, updated info about the Hitcon bug
Add .ruby-version and .ruby-gemset for RVM

Using this will strongly encourage RVM users (which should be most/all
devs) to use Ruby 1.9.3-p448 and a gemset named "msf"
Remove gitignore, change to metasploit-framework
Land #2362, update description
Land #2357
Land #2360

All the specs pass, and it's difficult to repo many of these cases to
see if bugs are actually here, but it's a good idea to enforce binary
regexs.
Land #2361, bump packetfu
Land #2365, .ruby-gemset and .ruby-version files
