- Added IronPython2.7 support
- Fix Makefile management for Python3
- Added relative timing for tests
- More stable smoothed ETA
- Refactoring _everything_ into one big `tqdm` class for even more subclassing fun

Added support for "restarting" a progressbar after a long pause without making the iteration rate go haywire. Simply call the `unpause()` method on the `tqdm` instance that is about to be restarted. Can also start `tqdm` skipping a number of steps specified by `initial` (without bias-ing ETA).

- Fully customisable output format using the `bar_format` keyword argument.
- Valid strings: bar, n, n_fmt, total, total_fmt, percentage, rate, rate_fmt, elapsed, remaining, l_bar, r_bar, desc
- Example: `bar_format='{desc}{bar}{rate:03.3d}'`
- Default: '{l_bar}{bar}{r_bar}', where l_bar is '{desc}{percentage:3.0f}%|' and r_bar is '| {n_fmt}/{total_fmt} [{elapsed_str}<{remaining_str}, {rate_fmt}]'.
- Solaris, FreeBSD support mentioned
- Link redirects circumvented
