#60 date/timestamp, keep x files

[halfgeek]

I know the development of dorgem is on a standstill, still these two -quite easy- features would make it just perfect>

-date (and / or) time stamp - obvious!

-an option to keep a number of captured images archived; let's say last 5 captured images, let's say cam01.jpg is the most recent one, cam02.jpg is older, cam03 is oldest (it only needs renaming the files every time a new capture is added)

thank for dorgem, it's a little gem!
