Squashed 'brjs-sdk/workspace/sdk/libs/javascript/browser-modules/' changes from 89e36a0..b22f15c

b22f15c Merge pull request #8 from adamshone/ie8-compatibility
1573902 IE8 Compatibility: converted the Object#keys() and Object#create() shims into private functionss. This means that browser-modules no longer shims anything. This is important because it must load first in any BRJS app, so anything that it shims cannot be shimmed by code that loads later on, such as the actual es5-shim library. That caused a problem because the Function#bind() shim in browser-modules does not work properly in IE8, whereas the version of Function#bind() in es5-shim does actually work.
aae845b IE8 Compatibility: both browser-modules and realm-spec include a Function#bind() shim that does not work in IE8 and also prevents modules that load after this one from shimming #bind(). Fixed by changing both so that they no longer use #bind(). Also had to fix the test setup to check for the existence of the console object before assigning it to origConsole.
e44f9cc Added a new 'Fixing Circular Dependencies' section to the browser-modules documentation.
3bc36be Made it obvious that the test within the sub-realms section was for previously introduced code.
3088917 Removing what appears to be Jekyll meta-data from README.md since it was actually visible within the page.
242c7a1 Thouroughly document 'browser-modules' so that people can properly understand how it works. @leggetter, this should be linked into the BRJS documentation.
