Display a different overlay when player or monster held by a web

For now it's a semi-transparent version of a normal web. It
doesn't look perfect but a fully-opaque version almost completely
masked the image underneath. Should perhaps get a new image for
this, with thinner strands and no or thinner outline.

player_caught_in_net no longer calls redraw_screen - otherwise
there would be a glimpse of a web over the player before the
item on the ground both existed and was set as "stationary" to
mark it as the trapping net (for thrown nets). The screen
seems to get redrawn shortly after anyway.
