With this patch the format paintbrush differentiate automatic character
attributes apply to character than those apply to paragraph.
Character attributes applied to paragraph are treat as paragraph format
when paragraph format are copied (and so apply to paragraph), and treat
as character format when paragraph format are not copied.

It also change the behavior of the format paintbrush on "restart
numbering" and "restart numbering at" attributes. With this patch those
attributes are simply copied… as expected.

GetCurParAttr : Get the paragraph format attribute(s) of the current selection.
GetPaMParAttr : Get the paragraph format attribute(s) of the selection(s) described by a SwPaM.

The advantage of these methods is that the take the named and automatic
format attributes.

Cleaned up SFINAE helper classes and added even more comments.

Without that, the following happens:

1) ShapeTypeContext::onCreateContext() in oox calls rAttribs.getToken()
2) FastAttributeList::getOptionalValueToken() in sax calls mxTokenHandler->getTokenFromUTF8()
3) OOXMLFastTokenHandler::getTokenFromUTF8() won't find the oox token and return OOXML_FAST_TOKENS_END

I verified that the new gperf input just adds tokens to the hash,
doesn't remove any.
