New: directories can have an index 'page'

I've decided that sometimes I really want a directory to have an index page, not just a list of the contents. So now I can, with the unimaginatively named 'index' view. It's mostly template based; the normal template uses inject::index to display an __index file. However, the view has several special properties:

• unlike other directory views, it is not inherited by subdirectories.
• it is only listed as an available view in the page tools area if there is a file called __index in the directory.
• if __index is a redirection, the index view will just generate a redirect to the target.

(Thus, the index view could be used to replace the wikiroot configuration directive.)

The index view is valid on directories even without a __index page in the directory. Right now the template just displays a normal directory listing in that case.

New: #pragma search ...

I got tired of the relative links in my blog drafts (written in an entirely different directory than their eventual home) not working. So, introducing #pragma search; this adds additional directories to search for pages when resolving relative links, both WikiWords and explicit [[...]] links. The directories listed in a search pragma must be absolute path names, and are searched only after the hard-coded possibilities have been exhausted (including the alias directory for WikiWords).

You can't have both a #pragma search ... and a #pragma pre in the same page, partly because it doesn't make any sense. (This is the simple way of getting out of handling multiple #pragma directives.)
