add new programName option to linux options

[lyimmi]

Description

When the program's executable name differs from the human readable name in a .desktop file sometimes the window manager won't draw the correct icon for it and if multiple instances are running the grouping can be weird too.

This PR aims to help with this issue by adding a new linux application option named ProgramName. This value is set when a new frontend instance is created by calling GTK's g_set_prgname() function.

Fixes #2800 (issue)
