Various updates, patches, plugins added and preemptively disabled.

- Added an exec plugin using the IdeOne API and immediately disabled it,
not nearly worth it's bloat cost. Uses SOAP and thus requires Suds.
- Added and disabled rbexec.py for now.
- Added an extra handler for bitcoin.py
- Added a timeout for down.py, to facilitate accurate results for sites
under heavy load.
- epeen.py updated
- stockquote.py now accepts company names as well as symbols like it was
originally meant to.
- Mapped .coldcall to tell.py for shits and giggles.
- Changed user agent to UA_Firefox in http.py for compliance with a few
stubborn APIs.
