Title: Enables proxy support

2 updates:

1) Modified `pub$makecall` so that it no longer overwrites global RCurlOptions. This is necessary to respect any proxy settings the user may have defined.
2) `postForm` may return a raw vector, which causes the subsequent call to `fromJSON` to choke, so I've added a line to convert its return value to character, if it comes back as raw.
