Add single char flag variants for most common flags (#69)

* Added single character flags for most common options.

* Added single character flags to docs. Removed -s and -t flags from skip and top because of conflicts with global flags.

* Changed some of the tests to use single character flags. Added a few new tests. Fixed itwin repository tests not being run. Fixed itwin repository tests. Fixed imodel connection create not passing display-name flag.
