Jean-Marc Lasgouttes c71e00090d Implement inset-dissolve (bug 2201)
* lfuns.h:
	* LyXAction.C: new LFUN inset-dissolve (bug 2201).
	
	* text.C (dissolveInset): new method.
	(erase, backspace): use dissolveInset.

	* text3.C (dispatch): implement LFUN_INSET_DISSOLVE using
	dissolveInset.
	(getStatus): disable LFUN_INSET_DISSOLVE if the inset has more
	than one cell.

NAMING RULES FOR USER-COMMANDS
Here's the set of rules to apply when a new command name is introduced:
1) Use the object.event order. That is, use `word-forward'
instead of `forward-word'.
2) Don't introduce an alias for an already named object. Same for events.
3) Forward movement or focus is called `forward' (not `right').
4) Backward movement or focus is called `backward' (not `left').
5) Upward movement of focus is called `up'.
6) Downward movement is called `down'.
7) The begin of an object is called `begin' (not `start').
8) The end of an object is called `end'.
