BaseX server startup script (init.d)

An init.d script for basexserver. The server will load at system start,
and open the CWE database. (This depends on the CWE database having
already been imported into BaseX, with the appropriate name.)

This script should be placed at /etc/init.d/basexserver
Kintsugi settings file (store BaseX password, etc.)

Created a file to store common Kintsugi settings. Right now this is
mainly to store the BaseX password, but that should be deprecated in
favor of a password vault when we have more time.
