Module 91_sequence: add delay option

[spaceboy]

Hi there

Here is a small patch to 91_sequence, which adds a delay option to detect for example a press and hold of a button, and subsequent RE's can omit device name to reuse the one that matched previously.

Note: German doc is not updated (my German is suboptimal )

Thanks for review

Thanks for the patch. I shortened it by replacing the part after "if($hash->{TS} > gettimeofday())" with sequence_Trigger(), and added the german translation.

Perfect, thanks!
