Increase EventMachine dependency version to 1.0.7

[v0dro]

I'm facing some problems with building EventMachine 1.0.3 native extensions (a possible fix is given here.

Increasing the version to 1.0.7 (latest) fixes the issue.

And I think this issue arises only on ruby 2.2.0

My schedule doesn't give me enough time to really work on this project at the moment, but I'd gladly accept a pull request.

Sure thing!

Also could you tell me if there is anything specific that I should keep in mind during testing?

Same here, happend only with ruby 2.2.x . Eventmachine 1.0.4 (a later) fix this.

[elmatou]

EventMachine dependency could be withdrawn.
It is only used for PiPiper#spi_poll which could be done with a simple sleep in a loop. Other Implementations, with EventMachine, Celluloid, Cool.io, Thread, Fiber.... should be done in application code.

I agree with @elmatou. If we can move this into the actual app code then it should reduce complexity of the gem. But anyhow, the current changes going into 1.9.9 which hopefully should be released in the next day or so contains the latest version of EventMachine. So this issue should be resolved once that is released. I am going to go ahead and close this.
