Span Of Datetimes v0.1

I have a lot of situations at work when I have to test the span of dates. For example, software should automatically calculate the date in 160 days from sysdate. Or it should calculate the number of days between two dates. Usually I used different online calculators for that kind of stuff, but at last decided to write a Chrome extension (which is more convenient).

So, here is the pilot version of Span of Datetimes.

As always, the main point is in simplicity and speed: you can use this extension only with keyboard - completely without a mouse!

Useful things that may be interesting for users:
* Regexps for inserting dates and times:
Dates /([0,1,2,3][0-9])[\., \,, \-, \/]([0,1,2][0-9])[\., \,, \-, \/]([1,2][0-9][0-9][0-9])/
Times /([0,1,2][0-9])[:, \., \,. \-]([0,1,2,3,4,5][0-9])/
* Format for date input is european DD.MM.YYYY.
* Works with negative values! For example, add -1 days to 02.10.2013 will be 01.10.2013.

One thing that I really wanted to do, but didn't succeed - masks for input fields. I used a jQuery for writing a mask functions and it worked in usual HTML page, but it didn't work if a opened same page in extension mode. So it some kind of jQuery-extension integration problem. So I hope I'll do masks in next versions.

And useful tip about browser - you can configure hot-keys for extension in the Google Chrome: * open the extensions tab - chrome://extensions/; * Link "Configure commands" at the bottom;
* Choose an extension and type a shortcut.
