Changed process start time to use seconds since epoc
Changed history parsing to be in python

- BH_PREV_COMMAND is the output of the previous history line.
- Chop that line up in python since the number of spaces were inconsistent.
Check that we have wget installed.
Reinstall on top of the client if it's already installed.
Configured bashhub to use https by default

- More secured!
Changed from using wget to curl

- Wget is not installed by default on Mac :( curl seems like it's installed
  everywhere.
Changed profile hook to use if statement.

- Also changed to use curl instead of wget. Works for mac with https in that
  case.
No longer need config file copied.

Should be created by bashhub_setup
Create BH_ON_PROMPT_COMMAND

- should now work with existing PROMPT_COMMAND definition.
BH_COMMAND parsed in bashhub.sh, removed the parse from bashhub.py
Basic bashhub.zsh working.

- Still need to setup install to work with it.
Add sys.exit for exception
Updated bashhub.zsh to install script. Testing it out.
Updated install-bashhub for zsh

- installs to .zshrc
Added #ignore support to omit sending commands.
WIP to check pythong version.
