Create LinkCryptWS.py

Add support for linkcrypt.ws to pyload
If the Linkcrypt.ws folder is password protected, type the password to the unrar password field
KeyCaptcha is actualy not supported. The most Folders haven't just this Captchas so the plugin retry it 4 times.

I try to implement key-captcha and a better support for windows clients (JS didn't work well)
