Project documentation moved to per-project book in SemanticCMS format.
Added changelog as top-level project link.
Taglib tlib-version is now set automatically during build.
Unfortunately, we cannot include "-SNAPSHOT" on snapshot builds due to the requirement of "Dewey decimal"
for taglib versions. The unambiguous full version is annotated via comment.
Using standard filter set provided by SemanticCMS.
SessionFilter moved from main web.xml to web-fragment.xml,
so it can be ordered between other fragments instead of
always being top of the filter chain.
