Version bump to v0.9j

- Version bump requested by OEMs to easily determine whether the
firmware supports the new EEPROM reset feature. Other than that, no
significant changes.

   - Baudrate is now **115200** (Up from 9600). 
   - Homing cycle updated. Located based on switch trigger, rather than release point.
   - Variable spindle is now enabled by default. Z-limit(D12) and spindle enable(D11) have switched to access the hardware PWM on D11. Homing will not work if you do not re-wire your Z-limit switch to D12.

+##Update Summary for v0.9j
+  - **Restore EEPROM feature:** A new set of restore EEPROM features to help OEMs and users reset their Grbl installation to the build defaults. See Configuring Grbl Wiki for details.

 ##Update Summary for v0.9i
   - **IMPORTANT:**
-    - **Z-limit(D12) and spindle enable(D11) pins have switched to support variable spindle!**
     - **Homing cycle updated. Locates based on trigger point, rather than release point.**
     - **System tweaks: $14 cycle auto-start has been removed. No more QUEUE state.**
-  - **New G-Codes:** Additional probing cycle commands G38.3, G38.4, G38.5 now supported. G40 cutter radius compensation cancel. G91.1 arc IJK distance mode incremental. G61 exact path mode.
-  - **CoreXY Support:** Grbl now supports CoreXY kinematics on an introductory-level. Most functions have been verified to work, but there may be bugs here or there. Please report any problems you find!
-  - **Safety Door Support:** Safety door switches are now supported. Grbl will force a feed hold, shutdown the spindle and coolant, and wait until the door switch has closed and the user has issued a resume. Upon resuming, the spindle and coolant will re-energize after a configurable delay and continue. Useful for OEMs that require this feature.
-  - **Full Limit and Control Pin Configurability:** Limits and control pins operation can now be interpreted by Grbl however you'd like, with the internal pull-up resistors enabled or disabled, or reading a high or low as a trigger. This should cover all wiring and NO or NC switch scenarios.
-  - **Additional Compile-Time Feature Options:** Control pin state reporting, force power-up alarm state, GUI reporting mode, and more.
