Fix escape handling in find tool bar.

It was explicitly handling the escape key for "return to current
document find", which is wrong since the shortcut for "return to editor"
(which it replaces) can be changed.
The correct thing is to register an own action for "return to editor"
for the find tool bar, overriding the default behavior.

Fix 'Run CMake' button text.

It raises a dialog, so it needs an ellipsis.
