Mail check every X minutes added

[David Pickens <dpickens iaesthetic com>]

Hey all,

I added a mail check every X minutes option this afternoon.

Let me know what you think.

BTW, I disable the Entry widget for minutes when the option isn't checked,
but I'd also like to be able to 'gray' it out -- is there any way to do
this?  Also, I restrict the minutes to 2 digits, but the entry space
remains large -- any way to narrow this?

I'll add the options for the progress window soon.

David
