Finish Raintale GUI script for Tell Story With Twitter

[shawnmjones]

The code already exists for doing this in Raintale. It just needs to be exposed so Wooey can render its GUI properly.

We need to update the Tell Story With Twitter script to apply the TwitterStoryTeller class to generating these stories.

I know that some of this work has been accomplished already because we already have test stories on Twitter. It likely just needs to be checked in.

I have now pushed the script which handles this to the wooey-raintale branch.

https://github.com/oduwsdl/raintale/blob/wooey-raintale/raintale-gui/scripts/Tell%20Story%20With%20Twitter.py

Tested the functionality multiple times and it seems to be working as excepted.

• Twitter story was generated only for 7/15 submitted mementos. We need to check on that.
• It also takes a really long time to generate the story.
• We need to let the user know that the process is going on while they wait. We should print what's happening onto the CLI.

After Friday's meeting, @himarshaj showed that this works. There appear to be issues with some URI-Ms not responding in a timely fashion. We will have to make a separate issue if this comes up again.
