lots of updates...

Deleted a lot of unnecessary files.
Weather now working thanks to wunderground api. nighttime icons don’t
display yet, requires another api call to determine sunrise/sunset
times and change icons accordingly.
Added a drop down menu. So far only controls weather location, weather
display and update interval for cpu/ram/net data.
Javascript refactored and updated.
Consolidated similar php files into one php ‘query’ file - getData.php.
Added extra details such as CPU frequency, governor, etc.
Also some smaller changes based on best practices/things I’ve learned
since beginning this many moons ago in a land far far away.
