Allow disabling double tap to reduce single tap delay

Currently there is a slight delay when pressing the button to turn the relay on, which is expected since the software needs that to distinguish a single from a double tap. This is very noticeable on a Sonoff Touch.

Since Espurna already goes into AP Mode if the wifi connection fails, disabling the double tap and getting instant single tap would be great!

This will require to change the DebouceEvent library. Changing the CLICK_REPEAT_DELAY setting to 0 in the DebounceEvent.h effectively removes the double click functionality and the library reports the clicks immediately.

Could this be a parameter passed to the library instead of being a constant?

I've just updated both the library and the ESPurna code to be able to pass the repeat_delay value in the constructor of the library. Check #0535fce in dev branch.

Oh that's cool! I've not setup the build environment yet (I'm using the compiled files here on bitbucket), but I'll try it if I set it up.

By the way, would this be configurable trough the web interface?

Yes, it can be configured from the web interface.
