BQ (r24): support for click apps which needs to run in a terminal

[Matthias Apitz]

There are terminal applications (for example the MUA 'mutt' or the Telegram client 'telegram-cli') which need a terminal to be used because they have a command line based input/output type. At the moment it seems to be impossible to create click apps due to missing support to launch the app inside the terminal; while the .desktop file have a parameter for this:

Terminal=false
it gives an error on registering click app if this is set to 'true':

# click build mutt.click
Successfully built package in './com.ubuntu.developer.mapitz.ubuntu-mutt-app_0.1_all.click'.

$ sudo click register --user=phablet com.ubuntu.developer.mapitz.ubuntu-mutt-app 0.1
** (process:1270): WARNING **: Desktop file '/opt/click.ubuntu.com/.click/users/phablet/com.ubuntu.developer.mapitz.ubuntu-mutt-app/ubuntu-mutt-app.desktop' is set to run in a terminal, not copying

I think there is just a missing feature in Unity 8 and it should (when set to 'true') just start something like

   terminal -e foo

where 'foo' is the value from the 'Exec=foo' parameter of the .desktop
file. This way it works in all other desktop I'm used to use.
