Beta fixes - alignment.

Screencast for node data and toolbar: https://screencast.googleplex.com/cast/NDYzMzgwNzcwNDU1NTUyMHw5YzNlNWVlMi1kNA

Node data view:
- ensure property value (and old value) are always to the right of the colon
- rename data view components to better reflect hierarchy/property tree nodes

Toolbar:
- fix the left ('Winscope', download info)  and right (upload new + 3 icon buttons) groupings so their contents are always fully visible at any level of zoom
- ensure trace file text does not overflow into trace icon on its left or upload new on its right
- fix height of toolbar so it no longer changes to fit items

Screencast for timestamp: https://screencast.googleplex.com/cast/NTQzNjAwNTcwNzQxNTU1Mnw1ZDJlOGRhZC0zNA

Timestamp buttons:
- Keep timestamp all on one line
