Added logging module

[cornusandu]

Added a separate logging module. This allows for:

• disabling low-priority logs
• disabling alert() calls (for testing)
• console messages formatted with built-in timestamps and log levels
• dispatching between console.debug(), console.info(), console.warn(), and console.error() instead of just console.log() and console.error()

I've dealt with the merge conflicts. This is ready to merge.

Please tell me if you'd like any modifications to be made.

Working on a bigger change to all scripts for locale. So i recommend waiting until thats done and then fixing the conflicts

Alright. I would appreciate it if you could let me know if you'll merge this PR, though, so I know whether to later fix the conflicts or leave it as-is.
