Create a random instance ID using Math.random instead of deriving it
from the RCON password with a hombrew hash algorithm. Remove
stringUtils as it's no longer needed.
Simplify getNewestFile by converting it to an async function, use the
fs-extra promise based fs functions and remove the files argument as
well as the callback.
Refactors the tests as well to use the test/temp folder.
Add symlinkMods function which takes an instance and a shared mods
folder as input and updates or creates the instance mods folder from it
by symlinking the mods in the shared mods folder to the instance mods
folder.
On Windows this uses hard links as the symlinks require elevated
privileges.
Add missing.js test files that requires any files that currently does
not have any unit tests defined for them. This should hopefully make it
so that when unit tests are added for parts of these files the coverage
will increase instead of decreasing.
Note that this does not include CLI Tools/ as those are not testable.
Replace the instancedirectory variable with an Instance class that holds
the directory and has a .path() to get paths relative to the instance
directory.
Change the ugly global slaves object to be a member of the db object and
implement the items database as a separate integrety verifying class in
lib/database.
