#935 Patch for openbox-lxde (major improvement)

[laf]

While working on MX NoFrills, my custom distribution yet to be released I was annoyed by two things:

1. openbox-lxde used an lxde-rc.xml instead of openbox's rc.xml which would especially be problematic if someone used obmenu-generator; in that context and given how popular obmenu-generator is, it was perhaps an intellegent decision at the time that has become stupid.
2. openbox-lxde would start openbox without openbox's autostart, again perhaps that was intellegent at the time, but everyone prefers to use the openbox autostart; at least give them a choice.

And so I changed openbox-lxde to the following: #!/bin/sh
exec openbox --config-file $XDG_CONFIG_HOME/openbox/rc.xml --startup "/usr/lib/x86_64-linux-gnu/openbox-autostart OPENBOX" "$@"

This ensures the standard rc.xml is used from openbox and openbox's autostart is iniatiated as well.
But I didn't like that openbox-autostart provided two other kinds of autostart, so I deleted those entries, but that is a matter of opinion. The amendment to openbox-lxde is a matter of fact; it is simply superior. Why turn people away from LXDE due to your failure to properly integrate openbox? This is stupid. Merge the changes.
