Change subject: Don't change config during toolbar setup
......................................................................
Don't change config during toolbar setup
Problem: When the toolbar is created twice with the same config object, the
second time around the tools are still bound to the old surface
Reason: The tool config is overwritten such that symbolic names of tools are
replaced with instances of tools, bound to a specific surface. The second time
around, the creation fails (silently in a try-catch) and then the already
translated list of tools is used to create a new toolbar filled with old tools
still bound to the wrong surface.
Solution: Leave the config object alone, and instead build a new list of tool
instances while iterating through tool names.
Change-Id: Ic43ec29173e556592bb3db9399ff83787e0a6857
Bonus: Don't fail silently. Using a try-catch to detect whether a requested
tool is supported masks other errors, and is evil. Instead, just do a lookup
and skip tools in which the lookup's result is falsey.
