Added unicode/plaintext toggle

- Added the $IDENTIFIER value that determines if unicode or plaintext is
used for function identifiers
- Cleaned up scripts with the help of shellchecker
- Fixed dwm_status so that other drives mounted within /home are ignored
- Replaced unicode codes with actual unicode in the source. For some
reason the codes didnt work on my Void machine
- Updated readme

+## Features
+* Fully modular! If you don't want to use a function, no worries.
+* Lightweight! dwm-bar is written entirely in POSIX-compliant shell script so need to install a hundred different packages to get it working.
+* Options! You can decide to use either unicode symbols or plaintext for module identifiers with the ```IDENTIFIER``` value.

-## Usage
+## Quick Start
 Simply run the script and dwm should display your bar:
 ```
 $ ./dwm_bar.sh
 ```
+Most likely, you will need to change some values for functions to get them to work - these are outlined with a comment for functions where this is likely the case.
 If you would like your bar to be displayed when X starts, add this to your .xinitrc file before launching dwm. For example, if the script is located in /home/$USER/dwm-bar/:

+You can also decide to use unicode or plaintext identifiers for functions by altering the ```$IDENTIFIER``` value. For example, set to ```"unicode"```, ```dwm_mail``` will display:

+[📫 0]

+Whereas, if it is not set it will display:

-* Ability to choose between showing unicode charachters or plaintext for identifiers in the bar
 * dwm_pulse function to control pulseaudio sound
 * dwm_bat function to display battery percentage and status
 * dwm_notifs function to show the last recieved notification in the bar
+* dwm_bluez function to show currently connected Bluetooth device using bluez
 * The ability to show network speeds and SSID in dwm_network
