Follow XDG Base Directory Specification

[Emiliaaah]

Problem

Currently most scripts use ~/.config or ~ as the base directory for their config location. I'm personally of the opinion that we should follow the freedesktop base dir specification, since this seems to be the widely agreed upon standard.

Affected scripts

The following list of scripts would be affected by this change:

• pgpg
• ikvmocr ($XDG_DATA_HOME specifically for this one)
• nbdig
• ipmikvm
• zabdig
• ipmiscrape
• wvpn

Solution

Most of these already use ~/.config (zabdig being the only that doesn't)

• Use $XDG_CONFIG_HOME as default config base directory
• fallback to $HOME/.config if this environment variable isn't present
• fallback to the old default of $HOME (where needed)
