Various desktop UI fixes:

 * Use xrdb to configure DPI and other settings (and stop relying on
 hardcoded font sizes).
 * Use higher-contrast, and thinner scrollbars (I never click scrollbars,
 they're just used as a reference).
 * Made the panel *slightly* darker.
Updated Host for the work VM (while on the VPN, the FQDN is not necessary)
Removed assia-inc systemd script: since it runs as root, systemd --user can't kill it.
Added bin scripts for arch32 chroot.
Added remmina config for the ASSIA VM
Centralized .gitignores
