Updated startup settings

* Added support for HiDPI devices
  * Only affects devices with a DPI >= 192
  * Most screen objects are doubled in size
* Updated .conkyrc
  * Vertical offset now set to 24 or 48 (to match URxvt)
  * Removed extra line after network adapters
* Updated .xinitrc
  * Removed dunst logic since `cbatticon` no longer sends notifications
  * Update .Xresources for all programs before `xrdb -merge`
  * Update hostname after `connect-to-network`
* URxvt windows are now based on a 16:9 ratio (instead of 4:3)
* Removed
  * .update_wallpaper (integrated with .xinitrc)
  * .urxvt_default_res (integrated with .update_dpi_settings)
* Fixes issue #45
