Python API documentation generation tool Code

- minor HTML change: in epydoc-log.html options table, use valign=top

- Fixed css bug that caused incorrect results in IE: "if you want
consistent rendering of lists between Explorer 5.x and Netscape 6.x,
you need to set both the left margin and left padding of the UL
element." -- <http://meyerweb.com/eric/css/list-indent.html>

- Updated the epydoc man page

- Added support for "--help TOPIC"
- If the target directory does not exist when the --include-log option
is used, then create it.
- Changed exit status for --fail-on-error etc from 1 to 2. When
exiting because of an internal error, use exit status 3.

- Fixed docstring typo

- Something has been merged. No need for further space crunching.

- HTML for fields cleaned up.
It should be easier now to change the page look providing a different CSS.

- The parser detects te trick::

if __name__ == "__main__":

and skips the block (or else testing stuff gets parsed).

- Fixed tooltip for class nodes.

- Fixed `ValueDoc.is_detailed()` when there are details in the variable,
but not in the value.
