#KT-2096 fixed

added a (disabled) test case to try out using the kotlin.browser.document property from generated JS

remove try/finally which leads to masking of exceptions occurring during generation of stub class [r=max]

#KT-2078 fixed

kotlin_lib.js modified, truthful description of MiscTest class added.

#KT-1960 fixed

added a test case for using the kotlin.browser package from JS (which fails so far, but its a start ;)

added the start of an experimental browser API so we can access the browser environment from a typesafe kotlin API which can be implemented on a JVM (e.g. with JavaFX) or compiled natively to JS to reuse the browser global variables

 #KT-2014 fixed

Fixed KT-2072: do not suggest to use type inference in Introduce Variable in case if expression type depends on expected type.

Replaced Usage of PathUtil.jarFileToVirtualFile() to PathUtil.jarFileOrDirectoryToVirtualFile(), removed the former.
