Summary: apply_to applies to modeling commands

Initial Comment:
With mged in GUI mode, switch to multiplane view, then
select Settings -> Apply To -> All Panes.

All commands will now apply to all four panes, which is
exactly what you want when turning grids and axes etc.
on/off.

However, editing commands will also be applied to each
pane in turn.  For instance, the command "r foo u bar"
will add the solid or combination "bar" to the region
"foo" four times; translation and rotation commands
will translate or rotate four times as much as
expected; "in" will tell you the solid you just created
already exists when it tries to create it again; "kill"
will tell you the solid you want to kill does not exist
when it tries to kill it a second time; etc.

In addition, passing the command to mged_apply turns
off user interaction, so incomplete commands result in
an error message instead of a prompt for the missing
arguments.

I do not know enough Tcl to submit a patch, but I would
like to suggest the following fix:

 - keep a list of all valid commands, marking each with
a flag to indicate whether it operates on the model or
on the view

 - in ia_invoke() in src/tclscripts/mged/mged.tcl, look
up the first word of $hcmd in that list.  If it is
flagged as a model command, or unlisted, ignore
apply_to and set $cmd directly to $hcmd.
