Tweak a few English string resources for clarity, punctuation, and spell...

...ing.

Remove unused GitAccess_ProjectForbidden/Account_Edit_AccountInformation string resource from all languages.

Please ignore or exclude **any** of the changes you don't like - much of this is subjective. :)

Note: Visual Studio automatically normalized a few of the non-English RESX files (by converting tabs to spaces) so the diff looks much bigger than it really is. Viewed locally with --ignore-space-change, the only changes to non-English RESX files are the removal of those two unused string resources. If you want me to go back and restore the original tabs to clean up the diffs, please let me know because it should be quite easy. (I didn't realize this had happened until I came to GitHub because I have --ignore-space-change set globally.)
