v4 dev server opens every category with every request

[nealey]

Description

When in devel mode (--puzzles), MOTHv4 appears to open unrelated dynamic (mkcategory) categories for even simple requests like "fetch this PNG from this puzzle in an unrelated category"

Steps to Reproduce

1. Create a puzzles tree with a mkcategory puzzle that sends something to stderr
2. Open an attachment in an unrelated category
3. Observe the stderr message

Expected behavior:

It shouldn't be opening other categories when you have no need for that category. Probably the code is doing some sort of expensive operation just to list categories out, when a mere top-level directory listing would suffice.

You shouldn't see that stderr message.

Actual behavior:

You see it.

Percentage of time it happens:

100%
