Fixes to selectors relating to the settings iframe. It appears that Trello added an iframe, and our selector was catching it and attempting to work with it which resulted in permissions errors which broke the saving of settings on Chrome, and broke the entire extension on firefox.
Bump version after the iframe fix (this will match the FF version).
If someone put spaces in their point sequence setting, it would not work. This change will ignore spaces.
Merge remote branch 'upstream/master' into badgeless
