Bug #0001138: General Template Work

1. adding "City" field to user registration page
2. made "Repeat Password" label in "inp_edit_passwords" block customizable
3. reload header after successful login instead of reloading whole page
4. raise "OnAfterLogin" jQuery event after Ajax-based login is made
5. FormManager was incorrectly detecting controls for date/time fields
6. "LogIn" button on "One Step Checkout" form just opens top login form because we can't nest HTML FORM tags
7. incomplete version of "One Step Checkout" page
8. FormManager was disabling "submit" buttons aross all page instead of current form only
