Talks

TODO: Describe model and functionality

Lifecycle of the talk can have multiple stages. Only talks that are marked as Published are displayed on the frontend of the application. Rest of the statuses are for organizers information only.

Talk statuses: * Call For Proposals - Submited talk proposal by the speaker. (Default status when submitting via frontend). * Draft - Talk added by admin, details of the talk are not finished, or speaker is not confirmed yet. * Approved - Talk ready to be published, but organizers do not want to display it on the frontend. * Published - Displayed talks on the frontend. * Rejected - Talk proposal did not pass. * Withdrawn - Speaker has to cancel the talk.
