[webappsec] TPAC 2016 reminder: 19-23 September, Lisbon Portugal

Since some in the group need to make travel plans well in advance, this is
a reminder that TPAC 2016 will be a bit different from previous years.
Instead of going back to Santa Clara in October, this year's TPAC will be
19 - 23 September in Lisbon, Portugal.

Mark your calendars and make your travel budget requests.
