Clean up help screen, get rid of util.py (#1027)

* More refactoring of cli.py

break up code from cli.py (now in jrnl.py) up into smaller functions
get rid of export mode
move --encrypt and --decrypt to commands.py
clean up the help screen even more
update flag name for import

* reorganize code, move around lots of functions

* clean up import statements

* move run function out of cli and into jrnl

* rename confusingly named function

* move editor function into editor file

* rename parse_args.py to args.py to make room for more args functions

* Fix error in test suite for windows

I accidentally flipped the conditional, so this fixes it.
