property setting

[Rune Zedeler]

It should be possible without any hacking to set properties in different 
contexts using the same macro.

The burning reason for this is the accidental macros - but also other 
macros might come in handy. I.e. being able to say \clef F in start of 
the score to get F-clefs in all staves would be quite handy.

I see two ways of doing this:

a) add aliasses to all context. I.e. "Current" to all contexts, 
"CurrentVoice" to all contexts except thread, "CurrentStaff" to all 
contexts except voice and thread.
This way one can say
\property CurrentStaff.blablabla
to affect the current staff if it is present, otherwise the inntermost 
context.

b) alternatively the \property command could be changed so that if the 
context was not found, instead of producing an error and do nothing, the 
operation was done on the innermost context. This way the clef-command 
would behave as desired without any changes to it.

Even though (a) gives the same flexibility I actually prefer (b) even 
though this might make debugging scores a little harder.
I don't really know why I prefer (b) actually, perhaps I just don't like 
the idea of all contexts being flooded with aliasses...
