LIM project source code management moves to Android repo

LIM project now uses Android repo tool to manage its repositories, to simplify developer source code access.

Detailed instructions on how to set up repo can be found here, in short,

mkdir ~bin
curl > ~bin/repo
chmod a+x ~/bin/repo

WIth that, to clone LIM project source, developer just needs to type the following,

cd workdir
repo init -u git://
repo sync

The entire source tree will be cloned into 'workdir', then at any subdirectory level, a simple 'repo sync' will pick up project latest changes.
