Set URL in history.replaceState/pushState

When <base href> is present, history.replaceState and
history.pushState behave inconsistent with relative URLs.
http://code.google.com/p/chromium/issues/detail?id=274024

Contrary to what one expect, passing '' as the URL parameter to
replaceState/pushState does not associate the currently active
URL with the history entry, but a path relative to <base href>.

To fix the issue, explicitly associate the current active URL
with the history's state.

Fix layout of main toolbar

Before this commit there were two main issues:

- In small windows, the zoom controls visually floated above the page number
  (e.g. 733px).
- In small windows, the (transparent) zoom container covered the go-to-page
  input box, which prevented one from using the input field to quickly navigate
  to a different page.

Update webL10n to latest version + features

Base version of l10n:
- https://github.com/fabi1cazenave/webL10n/tree/b18c753c6f
4 extra commits (expected to be accepted):
- https://github.com/fabi1cazenave/webL10n/pull/38

New features compared to mozL10n:
- Support for getting translated attributes in get()

The previous version of mozL10n was based on:
- https://github.com/fabi1cazenave/webL10n/commits/0c06867a75
- diff: http://pastebin.mozilla.org/3061694

To make it easier to update webL10n in the future, I will apply
the PDF.js-specific changes in a separate commit.
webL10n: Apply PDF.js-specific changes

Based on http://pastebin.mozilla.org/3061694

1. Remove "debug helpers" and use console.log/console.warn directly (top).
2. Remove page load initialization (middle).
3. Remove window._ alias (bottom)

The original diff contained an extra entry
"Adds fallback argument to the getL10nData;",
but this was already implemented in the rebased webL10n, so it's no
longer PDF.js-specific.
