======================
* creating/editing/deleting pages with eg spaces in the name has
been broken for a while, it seems - made some fixes in this area
* made the edit conflict message more helpful
* relaxed edit conflict checking: if your username & ip address
match the last editor's, the timestamp will be ignored. In other
words, you can no longer have an edit conflict with yourself.
This means eg you can backtrack in your browser, edit and click
Change again. This change may disable conflict checking amongst
anonymous users coming through a proxy.
* renamed the "username" property to "last_editor", added
"last_editor_ip", made these read-only in the mgmt. interface.
Existing zwiki pages are upgraded when viewed. dtml-var username is
still supported for backwards compatibility, but deprecated; use
dtml-var last_editor_or_ip by preference.
* stx workaround: trailing blank lines no longer cause unwanted
headings
* stx workaround: initial word plus period no longer becomes a
numeric bullet
* stx workaround: whitespace after :: no longer prevents example
formatting
* stx headings on first lines were broken - fixed
* fix for a 0.9.1 bug: with hierarchy display enabled, creating a
new page from a top-level page gave "typeerror"
* gopher: urls are now recognized
* renamed {wiki,page}_path to {wiki,page}_url in 0.9.2
