Support for chromium browser in linux

[macie]

Replaced execl() by execlp() and added support for chromium browser.

Thanks @macie. I'll get to this for Sprint 31. Sprint 30 closes down today.

I think this a good interim solution until we have a way to set the desired browser in preferences. Great work!

I believe this will help fix brackets issue #4720. As part of this support, should CloseLiveBrowser also be updated? It references the process google-chrome. At least on Ubuntu 13.04, when launching Chrome via the menu, the process I have running is chrome, launched via /opt/google/chrome/chrome. The google-chrome executable is still located at /usr/bin/google-chrome.

Yes, @macie we should also update CloseLiveBrowser to close the same instance that was opened.

@jasonsanjose I looked up the code, but unfortunatly I still don't know what CloseLiveBrowser does (where is used) and how to close it in smart way.

[jasonsanjose]

@macie it's used if the user already has Chrome open, but without debugging enabled --remote-debugging-port=9222. If we're in that state, we close the running instance of chrome relaunch with debugging enabled.

Looks good. Merging.

Tested with Chromium 28 on Ubuntu 13.04 64-bit.
