Description of problem:
Request add project to group infers the project version from the button / selector, but doesn't actually add this information to the email.
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. Sign in as a project maintainer, go to said project
2. Select a version, click Request to add project to group
3. Select a group in the dialog
4. Enter some text for the message
5. Press Send message
Email received contains the standard "user has requested" part, and the added message, but no information about the originating projet version.
The template should be something along the lines of "Zanata user '<username>' with id '<userId>' is requesting the project <projectname>(<projectversion>) be added to the group '<groupname>'"
