Filejoker.net and SendUrl.me - fix suggestions

[Filejoker]

Hello, 

Please set the `tryLoop` variable to `true` in the `addFileHost` function parameters for filejoker.net and sendurl.me. 
There’s a request-per-second limitation on the web server that prevents many links from being checked due to a 503 error.

Also, please modify `isAliveRegex` for both sites to `>Get Download Link` instead of `>Get Download Link<` - the download button text could be “Get Download Link or Watch Online”.

Thank you in advance.
