[Issue#168] Inch mode support.

Its would also be nice if it also converted the probing increments, and maybe even the macro’s, as well.

For your first question, there is a mouseover tooltip that shows the current unit of the increment button. The user input value will be updated when switching between G20 (inches) and G21 (mm). For example, 0.5 in <-> 12.7mm.

G20 inches mode

!2017-06-10 17 02 39

G21 mm mode

!2017-06-10 17 02 44

I can add units aside the number so it will be visible to users.

Second, there are some differences between Grbl controller and TinyG controller in CNCjs:
* The Grbl controller will send a software reset (ctrl-x) after running a file, so it will always force changing the units mode to G21 (mm).
“js
'gcode:stop': () => {
this.event.trigger('gcode:stop');
this.workflow.stop();
const activeState = _.get(this.state, 'status.activeState', '');
const delay = 500; // 500ms
if (activeState === GRBLACTIVESTATE_RUN) {
this.write(socket, '!'); // hold
}
setTimeout(() => {
this.write(socket, '\x18'); // ctrl-x
}, delay);
}
`

* For TinyG controller, I didn't send a software reset, only queue flush and clear commands are sent once a job has finished:
`js
'gcode:stop': () => {
this.event.trigger('gcode:stop');
this.workflow.stop();
this.writeln(socket, '!%'); // feedhold and queue flush
setTimeout(() => {
this.writeln(socket, '{clear:null}');
this.writeln(socket, '{"qr":""}'); // queue report
}, 250); // delay 250ms
}
`

Your suggestion is good, I can add configuration options that allows user to specify preferred units after running a file. For example:
`
Change the units after running a file:
[ ] Leave it as is
[ ] Revert changes to the previous units
[ ] Specify the units you want to use: G20 or G21

@AustinSaintAubin
The user input value in the Probe widget will be updated when switching between G20 and G21, what did you mean for “converted the probing increments”?

This looks great Cheton. Thanks!

Made some improvements to the axes widget in CNCjs 1.9.13, you will know the units that’s currently used.
