[MlMt] Update to Visualize bundle

[Sherif Soliman]

Hello MailMate users,

I pushed an update to the Visualize bundle today and thanks to Benny it 
is now available through the Bundles tab in MailMate Preferences.

Visualize lets you, well, visualize your email history. You can select a 
few messages (or a lot, I've tested it with up to 20,000 emails**), and 
plot those emails by sender or over time. You can also save those plots 
to pngs for archiving or sharing.

The update adds a line plot of daily totals to the Emails by Time page. 
You can choose the color for the scatterplot and line plot, and can also 
apply a moving mean to the line plot if the graph covers a large section 
of time.

Next up on my list is creating a statistics page that gives you 
different summaries/notes about the emails you selected, plotting by 
month and by year in Emails by Time (if the emails span more than one 
year), and visualizing recipient of emails, which is a bit trickier than 
visualizing the senders because each email has only one sender, but 
potentially many recipients.

Let me know if you have any feedback. You can report any issues on the 
bundle's GitHub issues page:

** I've actually tested it with over 100,000 messages, but it starts to 
take a few seconds longer to process and render at that point. Your 
mileage will vary depending on your machine.
