Fix python version detection in theme bobthefish

Note that currently both pypy and pypy3 have same display glyph.

Two fixes for tab plugin

iTerm2 nightly has an improved scripting bridge that exposes sessions, but until that ships, we'll have to use a hardcoded default and let users override.

Add tab plugin.
