Weathermap 0.98a

This version is for Cacti 0.8.8 ONLY - it doesn't work with Cacti 1.x. That is in development.

This is a roll-up of all the small bugfixes for the last couple of years, especially those that stop Weathermap
working with newer MySQL or PHP versions. There is a more substantial 1.0 release in the works, but I will backport any simple improvements or fixes to 0.98(abcd) releases. There are also small usability changes aimed at reducing repeat "error reports" in the forums.

Also, the license has changed from GPLv2 to MIT - this is intended to make life easier for those integrating Weathermap into something else, and also some enterprise users.

IMPORTANT NOTE - you may need to reset permissions on your users after upgrading, as I've
finally switched to the "new-style" plugin API that's been around for 5+ years. This handles
permissions differently, unfortunately.

IMPORTANT NOTE 2: THIS RELEASE DOES NOT WORK WITH CACTI 1.x! You will want version 1.0+ for that.

0.98a
FIXED - Works with PHP 7.x and 5.6 - removed all mysql_*() function calls, and use PDO instead
FIXED - Blank line issue with RRDtool 1.5+

NOTE: The installable plugin is php-weathermap-0.98a.zip, NOT the "source code" link below.
