Remove restriction on map label length [1484]

Guys - the only relevant bit is the part removing the restriction on name length at 30 chars. The rest is cosmetic.  We need this because our hi-res map label is otherwise truncated in the display.  The display is all within a scrollpane so if ever there was need for more room, it should expand fine, and we tested this.

Here are before and after pics so you can see the effect of this minor change.

Before: (label truncated)

After: (label fits fine)
