* Consolidate TKC projects and increase VIA keymap count to 4.

* Updated readme files.

* Removed config.h via limitation of 2 dynamic keymaps

* Reduce dynamic keymaps from 4 to 3 due to EEPROM space limitations.

* Update dynamic_keymap.c

* Restore 4 dynamic keymaps for VIA in TKC projects.

* Update quantum/dynamic_keymap.c
