Bower install fails due to mismatch of Singularity dependancy version.

[md-2]

I believe there is a typo in https://github.com/at-import/Singularity-extras/blob/1.x.x/bower.json#L11 where the singularity version is 1.2.0.rc.1 which does not match "version": "1.2.0-rc.1" in https://github.com/at-import/Singularity/blob/v1.2.0.rc.1/bower.json#L3.

Below is the error I get when adding "singularity-extras": "1.x.x", as a dependancy in my projects bower.json file and doing an install.

bower singularity#~>1.2.0.rc.1             ENORESTARGET Tag/branch ~>1.2.0.rc.1 does not exist

Happy to provide a Pull Request to fix or if I'm doing something wrong, advice welcome!

Thanks.
