Arrow-Keys are not immediately reflected to remote prompt about pwncat

This was an issue that I simply hadn't noticed. Thanks for the report! It will be fixed when the current working brach is merged back to master, which will be relatively soon.

For anyone who is interested, I used to have both ends of stdio unbuffered, which caused some other issues. In response, I removed the code which set the stdio streams to unbuffered. This meant that the select loop which processed user input could only read one byte at a time. This was fine in theory since if all of the data wasn't read off the buffer, the select loop should immediately notify of available data again (effectively looping through all available data). Oddly, this wasn't happening.

To fix it, I made only stdin unbuffered, and now do a larger read in the select loop to account for multi-byte key-presses (like the arrow keys). I was able to reproduce this report before, and it appears to be fixed for me in the modules branch.
