#node/250497 - shanwa, thank you--I didn't realize that hosts are disabling URL access through the file_get_contents.

Hopefully hosts that disable URL access through file_get_contents have enabled cURL functionality. I have coded the script to more intelligently determine if it is able to use cURL functionality (a optimized alternative to file_get_contents).

Also, I removed the {} around the field names in sql statements; this fixes problems with anybody that is using database table prefixing.
