commit 7b9b1d400c9e818fff69f8127e0efd49f7f8409e

libide: start on IdeSourceView
There is a lot to move down here, but getting it into libide will generally
make things a lot nicer for scripting and consuming libide.
Other todo's involve moving snippets down.
Emacs/Vim mode are a tough choice. I haven't decided where that should
go yet.
Eventually, we should be able to make a very basic example using the
test application included. Once that is done, things are a candidate to
merge with Builder UI layers.
