Many changes and new features:

* Make reminders be its own dataset rather than tied to current string.
 * Add support for repeated reminders
 * Make reminders be a feature that can be turned on and off
 * Add syntax highlighting for code blocks (right-click to set it)
 * Add a Pomodoro-style timer for measuring time spent on a task (stopping the timer offers to log it to Time Log)
 * Add ability to create markdown tables. Right-click to edit the table in a friendlier table dialog
