Jack Humbert d9e4dad0a8 Makefile redo & other features ()
* .build containment implemented

* no destructive variable setting - builds in either folder

* make from 3 places

* cleans before each build
* make from root with keyboard=keyboard, keymap=keymap
* make from keyboard/keyboard with keymap=keymap
* make from keymaps/keymap
* only implemented on planck

* adds color diag to avr-gcc

* makefiles for all plancks, clean-up

* quick build-all makefile for plancks

* reformatting of make output (colors)

* color toggle, tmk path corrections

* correct if statement for color

* move config.h to main makefile, updates preonic, atomic

* format update, all keyboards targets

* makefile optional for build all target, alps and arrow_pad updated

* alps updated

* make planck default, trying out travis recipe for all-keyboards

* all-keymaps target, different travis recipe

* updates alps64

* updates keyboards to new format

* updates clue* projects

* all projects updated, specialise EZ .hex, let .hex through

* updates travis

* automatically find root, keyboard, keymap

* silent echo, cleaned-up mass make output

* updates all keyboards' .hex files except EZ

* Rename Bantam44.c to bantam44.c

* Rename Bantam44.h to bantam44.h

* nananana

* adds six key keyboard

* does same to ez as rest

* updates send_string example

* brings ergodox_ez up to date

* updates template/new project script

* adds sixkeyboard

* adds readme for sixkeyboard

* adds sixkeyboard to travis

* filenames, gitignore mess

* define clock prescaler stuff manually

* make quick, size test example

* documentation and dfu-no-build
