Fix pageloader namespace

I seemed to be getting some conflicts with the regular pageloader as
defined by talos (even though I saw no reason why I should), but
renaming everything seems to make things happy, so let's do that.
Fix arg handling for page load output file

Need to handle a parameter with that arg, not just the arg itself!
Move initialization of STONERIDGE_RESULTS

It needs to be set to a proper object in srdata.js, so that the stone
ridge pageloader doesn't crap out when trying to save data!
Give me real access to the output file name

This way I can actually save files, instead of failing miserably!
