Renamed all JS files to TS files. Updated project file build action to TypeScriptCompile. #18
Converted all JavaScript code into TypeScript code. Moved some utility code to separate files. Most of the code is still is "any" type but we should fix this over time.
Compiled the project and tested to work with TypeScript code. Add the output JS files to project but the files themselves aren't going to be checked in. These get generated on project build.
Updated readme file with license and other details.
Merge branch 'master' of https://github.com/Khan/khan-windows-8

Conflicts:
KhanAcademy/pages/mainHub/mainHub.js
This file is converted into typescript code now. Made the change manually in that TS file.
