Removed classic GUI interface. Fixed typo with line number support.

- [config] Permanently removed classic GUI interface support. This
unintentionally created a problem where some users/GUI devs used this
compatibility mode and did not update to the new interface. So, there
were two interfaces in use, rather than just one like it was intended.
This removal should help everyone by forcing all GUIs to update and
updated GUI not having to support yet another interface.

- Fixed typo with line number support in jog mode.

+Subject: Fixed unintended laser mode pausing. Updated documentation. Min SS OVR lowered to 10%.
+
+- [laser] Tested a working version and pushed the wrong one for the
+last! 20161203 was pausing upon every spindle speed change. That’s not
+right. Fixed so nearly all motions are passed through and does not stop.
+
+- Minimum spindle speed override lower from 50% to 10%. Lasers could
+use the lower speeds.
+
+- Fixed a very minor bug related to G80 error checking. Allowed no
+error with non-modal motions with axis words. Not correct and fixed.
+
+- Fixed a compile error when disabling VARIABLE_SPINDLE
+
+- [doc] Updated some obsolete documentation.
+
+- [doc] Started a “Laser Mode” document that summarizes how Grbl’s new
+laser mode works.
