[FIXED] DatePicker with Slate style

[SSchaefer]

Hi,
if you use the DatePicker with Slate style, the next/previous month buttons have an "X" as icon. The other styles show "<" and ">" instead.

I've noticed a few missing styles in GXT items for slate compared to Ext2.01 - Darrell, you may need to run the 2 versions of the explorer demo and check these...

The data picker buttons are fixed in SVN.
