Add 2013/cable2/try.sh + update bugs + formatting

The try.sh script is as usual but it integrates some of the comments in
the previous set of commands in the 'try' section (in particular about
different typesets).

The bugs.md was updated with features, not bugs.

Typo/format check README.md file.
