Merge remote branch 'minrk/htmlfix' into trunk.
This branch implements a number of improvements to the HTML save
capabilities of the Qt console, and received extensive reviews. A
short summary follows, see the pull request page for full details, at
http://github.com/ipython/ipython/pull/170.
Some small issues in the HTML code I noticed when I started playing
with it.
* only rich backends support toHtml, so the html/xhtml exports
failed
* modules were imported inside functions
* relpath in image_tag was determined in platform-dependent way
* save dialog strictly enforced non-standard '.htm' file extension
* when selecting external PNG, the _files dir was always created,
regardless of whether there were any images
Fixes in this commit:
* export options do not appear in non-rich widgets
* module imports all at the top
* relpath uses platform independent os.path
* dialog uses standard '.html' by default, but allows any extension
* no _files dir is created if no images are to be exported
Closes gh-170 (pull request).
