Draw Tools Update

Updates to draw tools to add options menu (similar to bookmarks). Added
import/export/reset. Also added ability to set color of drawn items and
save color state
Merge branch 'master' of https://github.com/enigmaquip/ingress-intel-total-conversion into enigmaquip-master
some cleanups to #746
fix colour setting, broken by my changes to #746
draw-tools: use colour picker rather than input box
draw tools:
- broken localStorage data won't prevent plugin from loading
- import: validate data better on import - json parse before erasing current items, try/catch around whole import process, and existing save method writes back to storage
iitcm: use share interface on draw tools copy
removed bookmarks share button on iitcm
* call share interface from copy option
* a copy button and a share button are redundant since you can copy2clipboard from share interface too
* this way we stay consistent with the new draw tools options
