Subject: [PATCH] XMLHttpRequest: ignore case for request headers

Summary:
HTTP headers are case-insensitive, so we should treat them that way when they're being set on `XMLHttpRequest`.
Closes https://github.com/facebook/react-native/pull/1381
Github Author: Philipp von Weitershausen <philikon@fb.com>

Test Plan: Imported from GitHub, without a `Test Plan:` line.
