[WIP] Added link form as an option.

[reecer62]

(Closes #26)
Users now have have the ability to add a link to their talk which will be rendered as a tino dot (should I accept another field for the name of the link?).
Before creating the talk:

With link field filled:

After talk is created:

If the link field is left blank, it will default to talks.

The one thing that I am thinking currently is it is easy to just add another row for this as you have done, but have you thought about looking into parsing the desc field and see if it has link in it and if such inject the link?

For a lot of talks, they mainly do not have links so I am not sure if adding a new column for this would be the best solution.

As well, with my approach, given there is no auth other than checking if you are on clarkson's internet, it could be a security risk, but a cool idea could to set up some sort of moderation system for talks that include links and have a maintainer of Talks approve a talk. You could set maybe something up to send a text message with twilio or have a bot in discord request a specific user to approve a talk, but as expected it would take more effort but could be a good learning experience.

I am not pushing to do any one way, but just giving some suggestions that could be done.

Some notes I took at the cosi meeting:
Remove link field
Search for link in the description
Render description text as a link
CSS hover over effect for link href
Whitelist certain links as blue if good and red as bad
If red have a confirmation to open link
