Common now contains a notify function which uses notify-send to provide
a user with a notification when the function is called.
- Function takes 2 inputs, {summary} and {body} which are respectful
to the basic arguments for notify-send.
- Function returns an issue with required amount of arguments aren't
met.
- Default arguments are used with notify-send, no other interaction
is made possible.
Updated backup functions to only log STDERR to file, which files are
(de)compressed aren't fundamental to logging information and exact files
can be checked appropriately via other means.
Fixed bug with relative path being incorrect for operation of updater
when sourcing in common.
