I've made a complete change for GLPI 10-11 compatibility, aiming for the most native version possible without external dependencies (which reduces the file size). Only adjustments have been made to the text fonts. It's fully translatable and functions correctly, just as the original author described on their wiki (help buttons).
Updated the version to 1.7.0.0 to indicate the switch to native GLPI compatibility.
A document with all the details is attached.

Edited: for final fixes and more native look and feel glpi 10-11 style.
