* 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
