STORM-344 FIXED Fixed Speak button label shrinking when bottom bar has enough...

STORM-344 FIXED Fixed Speak button label shrinking when bottom bar has enough space for displaying full Speak label.

Bug was caused by counting only width added by last resize as usable for Speak button extending, so widening viewer window by few pixels many times when Speak is shrink would never let it expand regardless of available space.

- Added check for possible chiclet panel shrinking width- cause spare space goes to it when extending. If there is enough space to give from chiclets to Speak, Speak is extended.
