Please backport hexchat 2.10.2-1ubuntu3 (universe) from xenial

[Scott Sweeny]

Please backport hexchat 2.10.2-1ubuntu3 (universe) from xenial to trusty.

Reason for the backport:
========================
Several security fixes:
 * Disable SSLv3
 * Includes upstream fixes for POODLE vulnerability (CVE-2014-3566)

As well as some packaging improvements and many upstream improvements

Testing:
========
Mark off items in the checklist [X] as you test them, but please leave the checklist so that backporters can quickly evaluate the state of testing.

Tested on trusty built in ppa:ssweeny/ppa
