This is one large commit based on the UI changes I use.  Future commits will be more granular.

This commit's changes only affect the UI look and feel, and not back end functions or logic.

* animate elements have sub icons to show which type of animate element used
* more descriptive menu wording
* more descriptive icons (e.g. fingerprint icon didn't, give you a visual of what it does)
* icons that change depending if branch or leaf use the same icon.  There is already open/collapse buttons for branches.  I plan to use different icon colors to represent hidden and notes, so don't want another state that might be confusing
* zoom in and zoom out buttons added
* play button mostly working.  Still more work needed
* seek and jump buttons added to timeline buttons (seek increments depending on play/pause state not addressed yet)
* frame seek buttons moved to top with other timeline buttons
* help manual text updates
* Timeline and it's circle marker are now blue so as to be more prominent
* Help menu now has a Toggle Event Log option
* Some icon images were changed to be more descriptive
* Zoom buttons were rearranged to be more inline with the timeline buttons
* The main UI button bar was rearranged  to be in a more natural progression as to when a user would use that button
* Button groups are spaced apart without using a divider symbol.  This unclutters the UI, and should make it easier to visually jump to a button group
