Added support for remote files via plugin.

Browse Source 
This will allow to read and import data from remote locations, e.g.
LOAD DATA LOCAL INFILE 'htp://www.example.com' or
mysql_options(mysql, MYSQL_READ_DEFAULT_FILE, "http://localhost/test.cnf");
The implementation uses libcurl. For a list of supported URL types
see http://curl.haxx.se/libcurl/
