fix for ResManager button see #249

because Res Manager doesn't have a css file I made the theme update.
enable the default browser tooltip for the No Date icon for date TVs
possible fix to #262 when MM would throw an error on savedPanelId
revert change to manager.js, testing for undefined is not needed
removed old css styles - also see #232
removed old calendar files

I could not find any refereces to any of the files
removed mootols from login.html + some improvements

improv:
moved the css in login.css
spaced the forgot pass error response
html5 for login.htm
Merge pull request #269 from Cipa/develop
