travis-ci: second attempt at integrating a travis-ci.org system env var into our travis build configuration.

See r9080 for previous attempt.

Fix group meta query SQL manipulation.

The wildcard operators were acting too greedily, preventing some JOIN clauses
from being recognized and resulting in invalid SQL syntax. This problem had
previously been masked by ideosyncracies of WP's WP_Meta_Query SQL syntax,
which changed in [WP29887].

This change should be considered a band-aid fix for what is already a band-aid
fix. The proper resolution for this issue is to migrate away from the comma
syntax for JOINs used in BP_Groups_Group. See #5874, #5451.

travis-ci: specify IRC server/channel for notifications via encrypted key instead of server env var.

travis-ci.org support has told us that notifications are not sent from the build VM which runs our test script (which is where the env variables are set), and are instead from a seperate component which doesn't take the env vars into account. This is why the previous two attempts on r9080 and r9081 did not work.

Update XProfile admin area title CSS and JS to bring it up-to-speed with WordPress 4.0 expectations.

* Remove placeholder attributes on titles and rely on accompanying labels
* Show/hide title labels the way WordPress posts currently do
* Add 20px bottom margin to title wrappers to separate it from descriptions
* Tweak admin area form markup slightly to accommodate these improvements

Pass `$pag_sql` variable to 'bp_activity_get_user_join_filter'.

There are two instances of this filter, and the first one had this `$pag_sql`
variable passed to it, while it was missing in the second case (where there is
no pagination). For greater consistency in documentation and plugin
development, we match the format of the variables passed to each instance of
the filter.

See #5938.
