Major multi-purpose update.

[BoatrightTBC]

1. Fix all mysql calls to mysqli calls
2. fix all non-initialized variables (mostly in punchclock) causing warnings.
3. Replace broken phpweather (noaa discontinued the service) with saratoga-weather, which just looks nicer anyway.
4. Fix issues with path to the logo file, which is in timeclock/images but when running code from admin or reports or punchclock it was looking in admin/images etc... oops. Fixed.

Yes, I know this is a huge pull request, but the mysql touched almost every file. This now runs in php 5.5 with NO ERRORS ANYWHERE
