push_to_remote.bat

@REM much less dangerous version of git push, with (hopefully) no merge conflicts and well-organized, informative commit history.
@REM first checks that the working directory is up-to-date with remote, and has no uncommitted changes.
@REM Then soft reset, squashing commits, with backup branch.  
@REM squashed commit has same commit msg as last commit on build.
@REM limitation: not meant for multiple devs.  i.e. this works for my use-case - solo dev - and not much else.
