[webkit-dev] Also in the tradition of massive renames

[Maciej Stachowiak]

I'd like to propose the following directory renames for consideration:

Source/WebKit --> Source/WebKitLegacy (or alternately, LegacyWebKit for autocomplete happiness, but maybe not if we keep the LayoutTests name)
Source/WebKit2 --> Source/WebKit

Reasons:
- Matches the current names of the build products of these directories in Apple's ports
- Most non-Apple ports are based on WebKit2 but produce libraries that are just called WebKit

I've discussed this with folks internally at Apple to make sure there are no blockers. We believe we could execute this change sometime in the next few months, if there was general agreement. We believe SVN and git will be able to follow history across the move.

Regards,
Maciej
