Ubuntu: Modify cmake for click packaging and run on device

- Adds a new option UBUNTU_CLICK_MODE for use when either running
  trojita on device from QtCreator or building click packages.
  This option installs trojita to a contained location.

- Removed QCommandlineParser options from src/Ubuntu/main.cpp
  For some reason UbuntuTouch/Unity8 require --desktop_file_hint
  and --stage_hint to be passed when launching an app. Which
  the commandline parser was blocking these args. Since the
  commandline options were only really just setting the size of
  the qquickview we can safely just remove it and stick to a fixed
  size window.

- The click package manifests are located in qtc_packaging/click_ubuntu

- There is an additional trojita-ubu.desktop file specific to
  Ubuntu click packages
