Two branches on same machine get messy

[dandaka]

Now

1. User has 2 versions of a rep (master and beta)
2. Updates at the same time
3. Things get messy, since both updates use same folder

config.php →
define('TMP_DIR', '/tmp/spgd-'.md5(REMOTE_REPOSITORY).'/');

Should be

config.php →
define('TMP_DIR', '/tmp/spgd-'.md5(REMOTE_REPOSITORY+BRANCH).'/');
