Add effect speed support for RGB Matrix *No EEPROM yet* (#2922)

* Added Modular keyboards L,R and NUM

Created code modules for the 3 modules of the modular keyboard.
Original idea by MechboardsUK. Uses i2c implementation similar to lets
split

* Remove modular from master

This is to fix incorrect branching

* Add effect speed support for RGB Matrix *No eeprom yet*

Keycodes RGB_SPI and RGB_SPD have been added to increase and decrease effect speed.

Speed is not saved in EEPROM yet as per Jack's request.

* Update rgb_matrix.c

* RGB Matrix speed fix rgblight.h

* More fixes for rgb speed. Speed functions declared but not used in rgblight

* More travis fixes..

* Another one for travis..
