This uses net/url standard package (+ x/net/idna) to clean up URLs
instead of doing it via string manipulation. In particular, this solves
two problems:

1. In URLs like `gopher://example.org/foo` path was previously
   incorrectly detected by splitting on the first `/`, which is in this
   case a scheme separator.

2. Punycode is now decoded on display.

This is a prototype patch adding `/query` page for custom SQL queries to Betula.
It works, but the UI is sorely lacking: columns (and the table overall) is too
thin. `SELECT * FROM Posts` type of queries would probably also benefit
from displaying them as post feed instead of a table.

Previous version tried to apply 0->6->1..., which is wrong.
The right order is 0->6->7.
