It turns out that the SwDoc member of SwRenderData was not actually
leaked, but was deleted via the ViewShell member.

apparently SwXTextDocument::getRenderCount() may be called more than once,
so make SwRenderData::CreatePostItData() stop complanining and leaking
memory.

Currently when printing via SwXTextDocument::getRendererCount()
two STL containers in class SwRenderData are filled with bare pointers
to page frames from the layout.
These pointers are then used by SwXTextDocument::render(), which takes
one page out of the map and prints it via this non-ref-counted pointer.

This bizarre design will not be tolerated; instead, when printing a page,
iterate over SwRootFrm::GetLower() until the requested page is found.
This is slower, i.e. O(n^2), but at least it does not crash.

And elaborate slightly.

Fix for fdo#35190 - Impress writes invalid ODF for the table
styles (text:style-name instead of table:style-name).

Previously blinking was not exported in IE mode. IE still does not
support blinking (neither does Chrome or Safari) but the extra tag
does not make things any worse and allows importing the HTML back
to LibreOffice without loss of formatting.

Code is also simplified by removing conditionals for options that
no longer need to be disabled.
