Adds more window title options (#169)

* Adds options for windowtitle to toggle: custom title, icon and truncation

* Implements window title toggles: showIcon and showCustomTitle; Adds a new default title function and truncates it if specified

* incorporate new show label option into window title

* fix window title spacing to work with new styles

* allows truncation for custom window titles

* allows custom window title icon with default window title

* add option to show the window class name or title; refactor for consistency and easier readability

* remove redundant custom window title check
