Description:
If the current month has 31 days and the current day is the 31st, when first using  the date-time picker it will skip the next month when pressing the "Next" arrow if the next month has less than 31 days. Also, it won't go to the previous month when the "Previous" arrow is pressed the first time, if the previous month has less than 31 days.

How to repeat:
- set current date to October 31st
- log into dashboard
- click on graph thumbnail on Monitor tab
- click on Configure tab of popup
- select From/To radio button
- click on date-time picker button (calendar)
- click once on either previous or next arrow (top)
| if next, should skip to December
| if prev, should do nothing

It is pretty embarrassing for a date picker to not work on the last day of the month.  We really should investigate using a standard date picker from an established javascript library instead of a roll-your-own.

patch sent - minor issue with firefox mishandling date object in boundary case of incrementing month when on 31st into a month with less days.

patch was not internationalized

Internationalization of month names is a separate issue - will open a separate bug for it. Original patch should be committed if it hasn't already.

R8339 - committed to 1.2.1

reopen for 2.0 after tested

Test
1. Set your computer to October 31st
2. Open a page with a date picker like the events page
3. Open the date picker and click the next button
4. Note that the current month is now November
5. Change locale to Japanese
6. Open the date picker
7. Note that it opens the date picker and the calendar renders correctly

fixed in version 1.3.0.8371 - setting back to Verified until fixed in 2.0

r5924 - committed to 2.0. References overriding month and day name arrays that have not yet been created and will default to english. Will add localized date resources shortly, this was a separate bug.

verified fixed in build 2.0.0.5948
