Tried to simplify contours CSS so that it will compile (it was running
out of heap memory... this may be because I'm using an older CSS module
than Lotta was, but even she was getting very bad performance).
Removed generated sld of deleted stylesheet.
Updated generated SLDs (these may have changed just because I'm using a different version of the CSS module than Lotta did).
These are only whitespace (line ending) changes. They changed either because of initial SLD generation or (less likely) because of rewrapping, now being done on Mac instead of Windows.
Moved showcase page into root dir.
