Added a limit check in listTagInfo, and resolving this.

I'm not sure I agree with having two seperate tag clouds. I'd much 
rather integrate a filter to limit to galleries or images in either 
the existing results view or a more general serach function (something 
I've been meaning to do when I get the time).
That function already takes an array of tags to limit the search by 
and only returns the full tag list if it is omitted...however, I can 
see you point with large tag sets.  It does make sense to limit to the 
first, I don't know, 500 or so tags (by resource count) if there are 
none passed in.

After importing my galleries, I auto-generated tags from captions. I see that

words significantly differs from galleries and images so I keep them separated

. It can go as a separate page listed in Ansel menu.



btw: listTagInfo not limits any results. So just having the cloud block I am g

oing out execution time. I still haven't got time to deal with this issue but

you should really limit any possible long results.

I'm curious, why do you want to separate the image and gallery 
tags...and where do you see this page fitting into Ansel, as a Block 
in addition to the existing Tag Cloud block?

And of course the patch for Ansel_Tags

Show last 500 tags from images and galleries
