ofSerial prefixMatch search does not find Raspberry Pi UART under certain versions of Raspbian

[indicatesvoid]

I am unsure if, at one point, the Raspberry Pi's UART routed to /dev/ttyACM0, however, on my Pi (updated to latest via apt-get update/upgrade), it routes to /dev/ttyAMA0.

As such, the ofSerial class will skip over it when building a device list.

A simple fix would be to add the following line after line 168 of ofSerial.cpp:

prefixMatch.push_back("ttyAMA");

(curious if there is a reason ofSerial isn't just doing a blanket search for anything with a "tty" prefix? Speed? Safety?)

I think @bakercp has dealt with ofSerial, he might have some insight. His addon ofxSerial is pretty excellent though. 😉

Seems like a quick and simple PR to add -- ?
