[Request] Better handle hour/minutes typing in event creation/modification

[nicofrand]

When I create an event and click on the hour/minutes input, the hours are selected an I can directly edit the hour, which is cool. What would be even cooler would be that when I finish to type "10" (for example), the minutes are automatically selected. Currently, when I type "1030" the hour/minutes become "1030:00" whereas I'd expect it to be "10:30".

To resume:

• When hours are selected, if I type something with two digits, automatically select the minutes
• When hours are selected, if I type something with 1 digit but this digit is greater than 2, ex: 9, automatically enter "09" and select the minutes
• Do not let me enter something greater than 59 when the minutes are selected (even if this will be corrected later when validating the field)

Also, if you use tab when hours is selected, it goes to end date rather than minutes.
