[ewiki] ewiki.php changes

Jeff and I have made some changes to ewiki.php that I think we should
consider merging in, but I expect will take some disscussion:

1.  Move $ewiki_t up above the init plugins loop so that these plugins,
particularly ewiki_binary() can use ewiki_t()

2.  We moved $ewiki_data=&$data to the end of ewiki_page just before
unset($ewiki_data["content"]).  This was done because we did not want
the data to be available if the auth call was failed.  There was also a
problem if the binary handler was called.  The problem with the binary
was that the binary handler would not know about $ewiki_data and could
not clean it up like ewiki_page does by unsetting the "content" field.

3.  Inside ewiki_script() as part of the workaround for slashes in $id
an $asid is hardcoded to "view" I suggest using the EWIKI_DEFUALT_ACTION
constant.

I also posted a bug and fix to BugReports.
