Create Tags

# Date                                           Message                               Tag                      Commit
GIT_COMMITTER_DATE="2014-07-01 23:55" git tag -m "XWMM v4.1.0-rc1 for XBMC 13.x (Gotham)"  release/13-gotham/v4.1.0-rc1 4ca8c4a

GIT_COMMITTER_DATE sets the tag date to the same date as the commit being tagged to keep GH release page happy as tags are sorted by date committed not name.
