Fixed Here map plugin

Have you noticed that Here (Nokia) maps gives you a very badly tiled map since at least 6 months now?

Fixes Nokia Maps (Here maps) plugin by adding our own fixed version in /opt/qt4/plugins/geoservices/ and setting QT up for looking there first.
 The original plugin is not prepared for tiles bigger than 256x256 and the Here map provider started offering 512x512 tiles mid 2015, The old plugin still detects maximum size and sets part of the system up for 512x512, but will still load 256x256 tiles.
The result is a separate small tiles instead of a consecutive map area.

The screenshot is before the fix (app Meegopas) - Doesn't look very nice, does it?

PS! The phone will need a reboot to pick up the path to the patched plugin.
