* Update keymap & readme

-Keymap.c: Key combinations removed for resetting and added a new way to reset. Also removed unused timer code.

-config.h & rules.mk: Removed on kemap level (these were there for the key combo's)

-Readme.md: Changed the preview image and changed the description to reset the keyboard. Also added what connector type is used.

* Update readme.md

Better wording on how to get the keyboard in bootloader mode

* Update keymap.c

Switched + and - around, same with / and *.

 A compact 4x5 ortholinear keyboard made by Project Aqua and sold by Evil-cables.
 
 * Keyboard Maintainer: [AquaCylinder](https://github.com/AquaCylinder)
 * Hardware Supported: PCB, Atmega32u4
+* Connector: USB mini B
 
 Make example for this keyboard (after setting up your build environment):
 
     make emi20:default
 
-To reset the board into bootloader mode, press the physical reset button on the back of the PCB or use the keycombo (on layer 1) with the bottom left key and the second key from the top right diagonally.
+To reset the board into bootloader mode, press the physical reset button on the back of the PCB or press the bottom most left key to momentarily switch to layer 2 (on layer 1) and then press the key from the top right down one.
 
 The default keymap.c file has comments to help you on your journey,
