#93: drive the research menu with a mouse, and close the hole under it

Two separate faults, both reported on the same ticket.

The menu was inert under a mouse. Input reaches the tree as raw events
through BuildController._unhandled_input, because a Control that consumes
them through the GUI system swallows the drag, and the tree only ever read
touch events. That was invisible while the project set
emulate_touch_from_mouse and every click arrived as a synthetic touch; with
that setting gone, nothing selects and nothing scrolls, and there is no
other way to research anything on a desktop. The press and the pan are now
the behaviour, with touch and mouse as two ways in to them. Motion pans only
while the button is held - a hovering pointer must not drag the tree out
from under the reader - and the wheel scrolls, which is the first thing a
desktop player reaches for.

The panel also still had the buy button's hole in it. That button went away
in #83 and nothing moved down into the space, leaving ~180px of dead panel
below the readout while the tree above it stayed cramped. The readout moves
down 154px and the canvas takes the height: 1190px to 1344px.

The test drives clicks through BuildController rather than into the view,
since the missing piece was the routing - calling the view directly would
have passed against the bug as reported.
