Print out player hand before each choice.

It bugged me that I couldn't see my hand before each turn. So I made it do that.

Two other minor changes:
- Print a blank line after a game ends. I had a hard time realizing a game was over, since another one starts up right away.
- Use raw_input instead of input. Safer, and can't cause a syntax error. Let me know if I am missing some good reason to use input.
The card numbers are being printed all on one line. The space on the end of the print statement prevents a newline. One could use join to build the whole string, I generally prefer not to do that if I am just printing the string once. If you would prefer that style I'd be happy to convert it to that.

The current output looks like:
```
     0    1    3    4    6  
    Mus  Pes  Asn  Amb  Gen 
```
