Previously an outdated copy of the default readme. Updated to match the  Nyquist/DivergeJM format (DivergeJM is a split 5x12 implementation of the terminus_mini layout)

* Update makefiles to rules.mk

Renamed both Makefiles to rules.mk, removed references to makefiles

* Updated rules.mk

Inadvertantly removed important code from the rules.mk in previous commit. This has been restored.

changes made to 62349c33410671a33d4041d50cf27de1d6bdd9cf.

* Revert "Revert "Merge branch 'master' of https://github.com/mogranjm/qmk_firmware""

This reverts commit eae54fb3be2c60dffd704261f84bab98c9e06f93.

* Added QWERTY support to the QFR_JM

Implemented variable default base layer from the Planck default keymap.

* Update README to reflect QWERTY support

* Nyquist:DivergeJM - Update RESET location

Add a reset button to both hands, accessible when halves are disconnected.

* Typo fix

* Update DivergeJM

Switched master to Left hand,
Moved Reset key to a different location

* Added macros to send R pointer & dplyr pipe

Macros added as a string of keypresses, couldn't figure out how to get SEND_STRING to work.

* Added ADJUST -> QWERTY, DVORAK, COLEMAK

Re-implemented update_tri_layer fuctionality to reset base layer for Terminus_Mini & DivergeJM Nyquist keymaps to QWERTY, DVORAK or COLEMAK via the ADJUST layer.

Updated ReadMe files accordingly.

* Fix base layout diagram for Terminus_Mini

Remove split from diagram

* Changed the R operators to SEND_STRING, rather than keypress macros

* Added Dvorak to the QFR_JM keymap

* fixed duplicate row in Nyquist keymap

* Fix readme - LAlt location on mouse layer

* Set EE_HANDS to allow either Nyquist hand to work as master.

* Update R operator strings, clean up layering for terminus_mini, QFR_JM and DivergeJM

"<-" to " <- "
"%>%" to " %>% "

Also played around with the layering, removed unnecessary TAP_TOGGLE for LOWER and shuffled FUNCTION and MOUSE momentary actions to reflect layer order.

* Update bottom alpha row to output symbols on LOWER

This row now outputs the following (z -> /) when in the LOWER layer:
 <-
 %>%
{
[
`
|
]
}
.
/

* Updated readme files for QFR_JM, terminus_mini & DivergeJM

QFR_JM readme reflects correct LOWER bottom row symbol output,
terminus_mini & DivergeJM reflect correct command line make instructions.

* Add media keys to QFR_JM LOWER - Replicate QFR default functionality

* Fix issue with Mouse layering

Stuck on mouse layer because the wrong macro was assigned to the 'exit layer' key. Reassigned that key.
