This *should* allow for easy setup to work on any XDG-compliant desktop
environment. Just run `scripts/linux-setup.sh` and it will:
1. Determine the 'root' directory of the EDMarketConnector source you're
using.
2. Check you have `${HOME}/bin` in PATH and it exists as a directory.
3. Copy `scripts/edmarketconnector.sh` to there, replacing the string
`EDMC_PATH` with the 'root' directory.
4. Copy .png (icon) and .desktop files into ~/.local/share/... locations.
Then the desktop environment should have a menu entry for
"E:D Market Connector", which attempts to run `edmarketconnector`, which
should now be the shell script present in ${HOME}/bin.
