We're getting segfaults in places where this isn't checked. Also, add
some asserts so we can catch bad tool push/pop.
Removes all uses of GetCommandStr() and makes it private.
Also implements a uniform mechanism for avoiding auto-scroll after
a prime event or dialog which results in a mouse position at the
edge of the canvas.

The move tool can stack on others, so when we re-enter the previous tool
this caused another immediate action. We flag re-entry in the tool
stack to check for this and avoid unexpected tool starts
The problem is that wxEVT_CHAR_HOOK doesn’t do the key translation
properly. wxEVT_CHAR does, but we only get to that if we skip the
event at the end of the tool’s event processing loop, which most tools
don’t do. (Selection tools, point editors, pickers, and a couple of
others do skip, which is probably why this didn’t get reported earlier.)
I played around with a couple of ways to fix wxEVT_CHAR_HOOK. Most of
them don’t work, and the few egregious hacks I tried weren't cross-
platform.
So I’m changing it so that most tools now skip at the end of their
event loops. I left out a couple that I felt were high risk (length
tuning, for instance). But there’s still enough risk that I’m 100%
sure it will break something, I just haven’t a clue what.

Includes the addition of an onSetCursor() handler which must be called
from both the GAL canvas AND the GAL backend (at least on OSX) to prevent
cursor flickering between (for instance) pencil and arrow.
Also includes new architecture for point editors which allows them to
coordiate cursors with the editing tools (so we can switch to an arrow
when over a point).
We were running into various corner conditions where a tool's event
loop would exit while the tool was still active, or the tool would
get popped while we were still in the event loop. (A lot of these
had to do with the POINT_EDITOR's, but not all of them.)
The new architecture:
1) tools always do a Push()/Pop()
2) everyone is responsible for their own pops; no more stack-clearing
on a cancel
3) CancelInteractive events go to all tools to facilitate (2)
It's a bit of a hack because they're statically initialized and
so we can't make use of the _() macro. We do still want it in the
code, however, because the string harvesting is based off of it.
