Apache::TS::AdminClient broken in trunk

funtion get_stat uses a function called float if $resp[2] == TS_REC_STRING.
float is not a standard perl function and is not defined anywhere in the module.

I have created a patch that fixes this along with:

• Cleans up code
• perltidy's code
• Add a function: _find_socket that will check multiple locations to see if the socket exists if one is not passed.
• Changed required perl version in Makefile.PL from perl 5.10.1 to perl 5.8.8
