[Announce] Important information for OpenPisteMap users

Some OpenPisteMap bits are changing and this may affect third party software.
1. The tiles have moved to http://tiles.openpistemap.org. They are currently
being served from the old location as well, but this will be discontinued in
the following phases:
i) After a few weeks, tiles served from the old location will get a "please
update your software" watermark applied to them.
ii) A few weeks later, the old location will start returning "404 Not Found"
If you are operating a web site that embeds OpenPisteMap using the map.js and
opm.js scripts served directly from the OPM server then you *probably* don't
need to do anything. Other software will need updating.
2. Owing to abuse by a small number of users (no, using a robot to pull
down a third of a million tiles a week is not acceptable behaviour),
OpenPisteMap will start banning people who download more than 20,000 tiles in a
day or 40,000 in a week. As a point of comparison, the whole 3 Vallies resort
at all zoom levels covers around 9,000 tiles, so there shouldn't really be much
need to exceed these limits. If you have a specific reason why you need to
then please discuss it with me - bandwidth isn't free and a small number of
users are disproportionately using a lot of it.
Also, a polite request to robot writers: it is generally considered good
practice for robots to identify themselves in the UA string of their requests.
This is desirable so that the authors of buggy/misbehaving robots can be
contacted and therefore fixed, and also so that website operators can properly
estimate the cost associated with various clients. The vast majority of robot
traffic that hits OpenPisteMap spoofs a "real browser" UA string (most commonly
Opera, but most of the common browsers are represented too). If you're
responsible for writing one of these robots, please consider fixing your
software and presenting a suitable UA string.
