* Bug Fixes
* Fixed bug where a redefined `ansi.style_error` was not being used in all `cmd2` files
* Enhancements
* Enabled line buffering when redirecting output to a file
* Added `align_left()`, `align_center()`, and `align_right()` to utils.py. All 3 of these functions support
ANSI escape sequences and characters with display widths greater than 1. They wrap `align_text()` which
is also in utils.py.
