Removed all ads in free version (as an
experiment - they may come back if no one ever upgrades).
Fixed issue with Light Sensor trigger
ignoring constraints.
Tweaked cell tower trigger to fix issue
with some devices not detecting any cell towers.
Fixed problem where cloning a macro can
delete a random other macro on free version (when we have 5
macros).
Cell Tower trigger now takes into
account ignored cells.
Activity recognition trigger is no
longer experimental.
Other minor fixes.
