#2 support for long camera names

[John Loza]

I downloaded the flashcam utility to try and get my webcam to work with various flash driven websites. I got a strange error when running it. After looking at the source, I discovered that the name of my camera (uvcvideo/VF0540 Live! Cam Video IM/Video 0000:00:02.1) was too long for the variable allocated to hold it. I upped the size of the variable to allow for longer camera names. I also changed the "strcpy" to "strncpy" to prevent buffer overflow.
