Annotation Tools: Upgrading Share plugin from v1.0 to v1.1

**Background:** The Share plugin was apparently updated once the image annotation tool was introduced but it was never updated in the edX platform. This mitigates that.

**Studio Update:** None

**LMS Update:** This now fixes the bug that causes a problem when trying to "Share without saving." If the user shares after saving (i.e. from the viewer rather than the editor) the editor zooms in and pans to the appropriate location on the screen.

**Testing:** 
1. Install the [tarball](https://www.dropbox.com/s/r684ber7z4ddqtc/2014_T4.DPRfFs.tar.gz) as usual.
2. For each type of annotation tool try sharing on creation (share without saving) and then sharing from the viewer/pop up after creation. 
3. Try sharing without saving when creating a reply.
This should use triple-equals (`===`)
