Enable Evil^H^H^H^HJSON for PHP on Ubuntu 13.10

Summary:
Good news. Starting with Ubuntu 13.10, Phabricator can legally be used by evil dictators, mad scientists, and toxic derivative creators.

The JSON implementation prohibiting evil (http://www.phoronix.com/scan.php?page=news_item&px=MTQ0MTY) was ripped out and replaced by the Evil-friendly PHP license: https://github.com/remicollet/pecl-json-c/blob/master/LICENSE

Test Plan: ran the shell script, Phabricator no longer fails with "Call to undefined function json_decode".

Remove repository shortcuts

Summary:
Repositories currently have a no-UI "shortcut" feature which is only used by Facebook (and I'm not sure it's even used). As implemented, this feature is policy-oblivious and kind of nonsensical. Throw it away.

I'm open to reimplementing this, but I want to see some level of interest in it before I do. The new implementation would add shortcuts to each repository, similar to how mirrors work. My original plan was to follow this up with such an implementation (it's half-implemented in my sandbox), but as I worked through it I'm not sure it's really valuable.

Test Plan: Browsed repository list, grep.

Allow CelerityResourceResponse to hold resources from multiple maps

Summary:
Ref T4222. Currently, CelerityResourceResponse holds response resources in flat maps. Instead, specify which map resources appear in.

Also, provide `requireResource()` and `initBehavior()` APIs on the Controller and View base classes. These provide a cleaner abstraction over `require_celerity_resource()` and `Javelin::initBehavior()`, but are otherwise the same. Move a few callsites over.

Test Plan:
  - Reloaded pages.
  - Browsed around Differential.

Serve celerity resources from multiple maps

Summary: Ref T4222. Adds the map name to Celerity resource URIs, so we can serve out of any map.

Test Plan: Poked around, verified URIs have "/phabricator/" in them now.
