Offline Topo Maps iOS v6.1

This update does it all: adds features, improves the UI, and fixes bugs.

Improved Left Menu on iPhone (not iPad)
3D-Touch support - On the map, and saved screens.
of all the unlikely crashes in Offline Topo Maps, this release should fix about half of them, and we expect what was once a stable app, is now even stabler

Map Source Menus

the menus where you choose map sources and add map sources have been improved
map sources in your list now use an icon based on the exact map - different for each
you can now view a details screen about map sources in the app - includes a demo map, zoom range, description, and attribution
added a description for each map source - have fun browsing tons of maps of the world and history
remove default sources - you can now remove even default sources the app starts with, and customize your map layers perfectly (many people have requested this)
manage imported sources - view/add/remove sources you imported via the Add Map Sources screen too
