Bootstrap 3.3.0, jQuery 1.11.1, drop jquery.ba-bbq, update static/libs, drop IE7 support, new parse_qs/form_qs functions

update to bootstrap 3.3.0; bootstrap doesn't (never?) support IE7 so properly drop support

update to jQuery 1.9+, required by Bootstrap
(originally 5eb9005dec4ae6c5a5085fa10e68a55794ce76a7

drop jquery.ba-bbq.min.js which isn't compatible with jQuery 1.9+
* hashchange support is no longer necessary as this works in modern browsers without any shim now (no change needed)
* replace depaam with a new parse_qs/form_qs pair of functions that I just wrote

use parse_qs/form_qs in search pages, which I think also fixes a long standing bug with array values stored in the url fragment not being parsed right

update static/libs local copies of jquery and boostrap to the new versions, which I use in debugging to avoid network hits

I initially didn't realize that updating Bootstrap would require updating jQuery which would break jquery.ba-bbq.min.js and reverted the work in 37f7e2a7902bf62b85eebb427691748eecd2c8ab. This reverts that, plus takes care of making things work again.
