Cleaning sxhkdrc

- I divided the sxhkdrc file now in two sections:
    -   Start programs ( Super + <key> )
        + Zathura:  super + z
        + Emacs:    super + e
        + Dwb:      super + w
        + Firefox:  super + f
        + URxvt:    super + <CR>
        + Dmenu:    super + d
    -   Function keys
- Removing some old settings, which were uncommented
Creating a usable tmux configuration

-   My tmux modifier is now C-y
-   The bar is inspired by /u/earsplits setup:
    -   New windows are symbolized by an * in black
    -   The active window is symbolized by an * in pink
-   With C-h/j/k/l it's possible to switch through the panes (in vim you
    can also navigate with C-h/j/k/l though the splits -- seamless
    integration!!!)
-   Im using now C-M-l to clean the screen (and to not conflict the
    navigation through the panes via C-h/j/k/l)
The firefox binding conflicts hlwm

-   I changed the binding to start firefox to "super + o" to not
    conflict the fullscreen command from herbstluftwm, which is binded
    to "super + f"
Ditching the ugly dirty yellow for a very light yellow
Cleaning the Xinitr file
Theming zathura and dwb to matching hemisu
Changing gaps and padding of herbstluftwm
Adding ncmpcpp/error.log to .gitignore
Updating the oh-my-zsh and vim submodules
Reaaranging the sxhkdrc file for a bettter readability
Installing sublime-test-3
Adding some useful functions and rearranging

-   Adding a function to colorize the output of "dirs". With the command
    "stack" it's now possible to have a nice colorized output of the
    directory stack. The "dirs" commands is a shell buitin, so the
    aliasing is not so easily possible.
-   Adding some aliases to configure the config-files of tmux and minirc
-   Fixing the remove_orphans function
-   Outsourcing the script to reload the configuration-files of tmux and
    sxhkd from own scripts at ~/.bin as functions in the alias.sh file
Removing dwb-backup files & adding them to .gitignore
