* Add personal KC60 keymap

* Update personal KC60 keymap

* Keymap update 2018-05-30 01:53 UTC-7

* Added macro: T_PEEKR

* Added macro for MacOS Select All; modified MacOS function layer

* Added git branch-name macro

* Added GitHub signature macro

* Added readme files

* Added Quake 2 and System layers

* Refactored keymap readme

* Refactored to add userspace files; added Colemak layer

* Minor code cleanup; updated readme files

Decided not to make use of the Userspace feature at this time. Reverted its addition, and updated the readme files where needed (they were linking to userspace files).

* Updated per review comments by @drashna

I'm still not sure these work properly

+## Layers 4, 5 and 6: Quake 2 `_Q2`, Quake 2 Dvorak `_QD`, and Quake 2 Console `_QC`
+
+### Accessed by holding either `Fn` key and tapping the `/?` key, then tapping `4$`
+
+These layers were born out of the confusion I have had trying to use the in-game chat and the console in [Quake 2](https://en.wikipedia.org/wiki/Quake_II). When Quake 2 came out, alternate keyboard layouts weren't really a thing. As a result, all in-game text input is hard-locked to US QWERTY, regardless of what the operating system is using for its input method.
+
+I'm attempting to solve this by some creative use of QMK's macro feature. The keycode in the System layer that enables these layers, [`GO_Q2`](./keymap.c#L386), is a [macro](./keymap.c#L175-183) that sets the default layer to the QWERTY layer, then turns the Quake 2 layer `_Q2` on. The result is a partially-overwritten QWERTY layer, that has some keycodes with some creative layer switching.
+
+When I hit the `Enter` key (bound in-game to text chat), the [macro keycode](./keymap.c#L184-L191) I've created sends the keycode for `Enter`, then follows with enabling the Hardware Dvorak layer and its corresponding overlay. Now the game is in text chat mode, and my keyboard is in Dvorak. When I hit `Enter` again, another `Enter` [keycode macro](./keymap.c#L192-L199) is sent, which sends the message, then the macro brings me back to the standard QWERTY+Quake 2 setup. Hitting `Escape` instead runs a [macro](./keymap.c#L200-L207) that cancels the sending of the message, and undoes the layers.
+
+I have been testing this configuration for a few months. Sometimes I end up still in Dvorak mode without any text input systems (in-game chat or the console) running, but it pretty much always happens when I'm focused on the game, so I don't know the cause yet.
