Extracted files from official rstudio github

They were different than files pulled from Tom Wu's personal webpage. As such, took apart the
following file:
https://github.com/rstudio/rstudio/blob/44b1b2815b76013d5a2ba6e9a203ab52be7e5d9e/src/gwt/tools/rsa.js
and extracted constituent parts.
Prevent multiple requests from fufilling by timeing out
Move encryption to JS only in rstudio.js

Much better than waiting on reading the file from OS.
