Misc. Fixes for lastpass-python

[guilt]

Hi,

This pull request has some changes in it, including some SecureNote parsing code that was borrowed and improved. Update: Moved the lpass CLI to a separate repo (https://github.com/guilt/lastpass-python-cli)

It's to help someone who was looking for how to get some of the notes data in Python. Please adapt this to your convenience.

Thanks to all the authors who had written some of the original code I took this off.

Would love to see these changes, I am trying to replace lastpass cli's implementation. And use this library for a gtk application :-) so would love the possibility to have the same kind of settings to store the database locally and reauth when a specific time is elapsed :-) These changes allow me to create such thing :-)
