Making browsing easier

I've been doing some more work on the site, a lot guided by valuable feedback.

I am aiming for users to be able to browse themed albums in some form of structured, hierarchical way, but that's eluding me for now.

In the meantime I have implemented some changes which will, I hope, at least help:

1. when you browse the galleries all the empty ones are hidden, unless you own them. At the moment the pagination is an issue as you still get pages as if there were albums, but it's a start!

2. I have added a drop-down list of currently used keywords to the left-hand navigation. It's just sorted A-z, rather than structured in any way, and in time it will become seriously unwieldy, but for now it seems quite handy, and does give both a quick way into themed contant, plus a good feel for what's in the site. Try it on the left-hand side of any gallery page

3. more as perhaps a gimmick rather than anything else, I have added a link to 'Lucky dip!' which just gives the casual browser a quick way to get 6 random images as a taster.

Onwards....
