DateBox.setFormat buggy

[reinert]

There's a bug in the setFormat method of DateBox at L119.

Some unexpected replaceAll is being performed, altering default behavior of any format using "MM" segment.

I'll fix it soon.

[WARNING] If anyone is using setFormat with "mm" segment it will be broken after the patch

This bug, actually is pretty well intended.

DateTimeBoxBase has a processing changing formats.

I wonder why these processing were implemented???

Why not rely on default and expected formats??

I'm afraid of removing these processing and break existing projects.

I do need opinion form others.
