Editing a PC inserts incorrect spaces into argument

[andreas.faerber@…]

Q relies on the guest command line arguments in the configuration file being separated by single whitespace characters.

This is problematic because editing a PC without manual QEMU parameters adds a whitespace character before such an empty string, leading to a constantly growing file and inability to launch the guest.

An initial patch was provided to start tackling this.

But additionally, Q does not recognize every single-token parameter and tracking those is a tedious task. Instead, once initial fixes are in place, the argument parsing should be revisited to no longer rely on this string-explosion based on whitespace character, i.e. tokenizing quoted and unquoted strings, ignoring any combination of whitespace characters in between.
