Add predefined command line arguments to programs

[Karandra]

Description

Some programs can use command line arguments ton configure their behavior. Some of them has this as the only way to use their features. Often user need to quickly change some command line arguments to run program in different mode and it's really inconvenient to specify cmd-line args by hand every time (I'm looking at you, xEdit).

So I'm thinking of an option to specify list of known command line options. User would check required options and Kortex will format final cmd-line automatically.

That requires following:

• Either store cmd options with program entry or store them separately and link later.
• Specify format rules because different programs pareses their cmd-line parameters differently.
• Allow to specify cmd options order. Some programs are sensitive to options order (xEdit again).
