Arcanist - stop arc land if local is ahead of remote

Browse source 
Summary: Fixes T4291. Also pht user-facing strings.

Test Plan:
made a branch `foo` off master. made a commit and a diff in `foo`. switched backed to master and cowboy committed some thing. went back to branch`foo`, did an arc land, and saw the error message. went back to master, did a git resert --hard HEAD^1, went back to branch `foo`, and then successfully arc landed.

also ran arc help land and things looked good
