I noticed that the documentation for new developers was outdated and scattered throughout different places, so here's a little update on what I've being doing to merge those pages.

The "Submitting Patches" page was completely outdated [1], so I ported the more complete and up-to-date content from the source file docs/SubmittingPatches [2] to Confluence and merged it into the more recent "Pull Requests" page [3].

As the Pull Requests page was already long enough, I moved some of the new content to new pages:
* Commit Message Guidelines - https://freeswitch.org/confluence/display/FREESWITCH/Commit+Message+Guidelines
* New Modules - https://freeswitch.org/confluence/display/FREESWITCH/New+Modules

I also noticed there were two different sections with look-alike content: "Developers" and "Community > Contributing Code". I moved everything from the former (including sub-pages) to the latter.

Next actions:
* Remove https://freeswitch.org/confluence/display/FREESWITCH/Submitting+Patches (I don't seem to have permission to do that) 
* Remove https://freeswitch.org/confluence/display/FREESWITCH/Installing+Git - either Brian or Areski tagged it for deletion
* Remove [2] entirely (to avoid duplicate content), or just point it to [3].

[1] https://freeswitch.org/confluence/pages/viewpage.action?pageId=6587641
[2] https://freeswitch.org/stash/projects/FS/repos/freeswitch/browse/docs/SubmittingPatches
[3] https://freeswitch.org/confluence/display/FREESWITCH/Pull+Requests

Feedback would be appreciated.
