Support --since option for timeline and view cli command

[timofurrer]

Support --since option in timeline and view cli command.
The dateparser package is used to parse the since date: https://pypi.python.org/pypi/dateparser

Examples:

twtxt timeline --since yesterday
twtxt timeline --since "1 hour ago"
twtxt view --since "Fri, 12 Dec 2014 10:55:50"

Any concerns about this one?

[buckket]

Had to revert this as dateparser has some problems with it’s setup.py that breaks stuff on RTD (UnicodeDecodeError), for example. We also would incorporate many new dependencies, will think about our possibilities here :/

[timofurrer]

oh, shit .. I'll figure something out asap.

Is it possible to reopen this PR?

[timofurrer]

Could you open an issue at the dateparser repo about that?

[buckket]

Apparently it’s not possible to reopen a merged PR. Will double check if the error is really caused by dateparser, i.e. if they should change something rather than say RTD.

[timofurrer]

Okay, thanks. Are you fine if I submit the PR again and mark it as WIP?
To discuss further steps there and that no other person is working on the related issue..

[buckket]

Sure, go ahead! 👍
