[Clam-devel] showing output of system calls

[David García Garzón]

Annotator has the TaskRunner class which does the following.
- opens a DockWidget on the bottom of the MainWindow
- embeds a text editor in it
- executes a command with QProcess (not blocking)
- prints the command line in blue on the text editor
- prints the command output highlighting error output in red
- after termination prints 'Done'
- sends a signal to the main application with the result
- waits 5 seconds and closes the dock widget

I used a refined version of this task runner for a different project which 
allowed multiple processes and process dependencies but you can just start 
with this one.
