Off The Grid 2.0

This is still compatible with game update 1.2.0 and doesn't need a new version.

Rewritten to work on all lenses added by current and future mods. It does no longer need an update when someone creates a new lens mod.
The hex grid will now also be disabled again after a UI reload, for instance when changing certain graphic settings.

Special thanks to @beezany and @wltk for patiently explaning Javascript code to me.

Updated support for the Search Natural Wonders and Wonders mod version 1.5 by Seussnu. Because of changes in that mod in version 1.5, the grid was no longer hidden for their lens. This update fixes that.

Added the lens created by wltk's Detailed Map Tacks. That one will be unhexed now as well.

This is still compatible with game update 1.1.1 and doesn't need a new version.
Still compatible with game update 1.1.1 patch 1 as well.
