Fix #2533139
Remove all str[pos] character look ups with str.charAt(pos) for older IE
Update Promises tests to no use Error objects

IE seems to have an issue with using Error objects, so I removed the new
Error creation and simply return a String-based `reason`.
Caching arr.length and simplified the if conditional per ericf's suggestions.

Fixes 'not win8 app' test for IE6/7

IE6/7 was barfing deleting the Mock window.Windows object we set up
for the prior 'win8 app' test, resulting in "Unexpected event error"
in the log, and since hte window.Windows Mock object stuck around,
'not win8 app' returned true, instead of false in IE6/7
Potential fix for trac2533149. Testing indicates this will fix all parse errors in android 2.3.4.
