Uncaught db error if task description is too long

[dalers]

Entering 292 characters for a task description results in error message "MDB2 Error: unknown error" after clicking Save. If the text is only 184 characters is it saved correctly.

The cause seems obvious since the task description field in the tt_tasks table is defined as varchar(255), but it would be nice addition to display a helpful message instead (also adds confidence to know nothing really bad happened).

Thanks for a great app, I've been using it daily since August 2015! :-)
