Fix a bug related to editing an existing image.

SiteImage uploads have always allowed editing the image, without actually replacing the image.

I believe this is primarily to allow editing other fields, such as title if available. Despite the base Site package upload page having no further fields beyond the upload widgets, I've kept this behaviour for easier subclassing and use in existing pages. What this does mean is that we shouldn't replace teh existing object, unless new image is uploaded.

Don't quote numeric values as strings when building google analytics commands.

This fixes an error Google's Tag Assistant Chrome Extension points out on all our sites when setting _setSiteSpeedSampleRate
Better checking of numeric values when quoting.

This prevents strings that are also numbers from being used as a number in the analytics commands. Thanks to @gauthierm for pointing it out.
