Fix bug 4037 and related problems. The patch has been cleaned up a bit from the one posted to the list. The basic idea has two parts. First, we hard code an "empty layout" (called PlainLayout, for want of a better name) in TextClass and read it before doing anything else. It can therefore be customized by classes, if they want---say, to make it left-aligned. Second, InsetText's are divided into three types: (i) normal ones, that use the "default" layout defined by the text class; (ii) highly restrictive ones, such as ERT and (not quite an inset) table cells, which demand the empty layout; (iii) middling ones, which default to an empty layout and use the empty layout in place of the default. (This is so we don't get the same problem we had with ERT in e.g. footnotes.) The type of inset is signaled by new methods InsetText::forceEmptyLayout() and InsetText::useEmptyLayout(). (The latter might better be called: useEmptyLayoutInsteadOfDefault(), but that's silly.) The old InsetText::forceDefaultParagraphs() has been split into these, plus a new method InsetText::allowParagraphCustomization(). A lot of the changes just adapt to this change. The other big change is in GuiToolbar: We want to show LyXDefault and the "default" layout only when they're active. There are a handful of places where I'm not entirely sure whether we should be using forceEmptyLayout or !allowParagraphCustomization() or both. The InsetCaption is one of these. These places, and some others, are marked with FIXMEs, so I'd appreciate it if people would search through the patch and let me know whether these need changing. If they don't, the FIXMEs can be deleted. git-svn-id: svn://svn.lyx.org/lyx/lyx-devel/trunk@22966 a592a061-630c-0410-9148-cb99ea01b6c8
