[WebProfilerBundle] Small bugfix in CSS: don't make links bold.

If the CSS in your application has something like `a { font-weight: bold; }` to make links bold by default, they will also show up **bold** in the profilers toolbar, which doesn't look right. This patch explicitly sets the font-weight to 'normal', as it should be.

Force Luhn Validator to only work with strings

The Luhn Validator fails to work with float or large integers (internally turned into float by php, depending on precision setting).
This is problematic because developers might use number or integer form fields to capture credit card data, which will lead to a validation error even though the form input itself was valid. This commit makes validator throw UnexpectedTypeException on non-string input to avoid this confusion.

[Console][ProgressHelper] Fix ProgressHelper redraw when redrawFreq is greater than 1

When using a ProgressHelper object with redrawFreq > 1, there are situation where redraw may never occur.
E.g.

    redrawFreq = 2
    setContent = 1
    advance(2) ... the redraw event is detected by 0 == current % redrawFreq.

I've tested the patch against phpunit and my local environment.

Maybe, a new test can be implemented to avoid the previous example, but I'm not familiar with mock object... :)

Request::overrideGlobals() may call invalid ini value

According to http://php.net/manual/ja/ini.core.php ,
there's not variable_order, but variables_order (with trailing "s").

Perhaps it breaks BC for some developer who unsets
'request_order' ini value and sets 'variable_order' manually?
