Read only attribute

[Nadim Khemir <nadim khemir net>]

Please, please, please,

Could the dev team _stop_ doing a backup and allow the modification of "read 
only" files. I understand that this is a unix file attribute problem and not 
a Dia problem (that's why I haven't reported it as a bug) but applications 
must also play the game and not change file names for files that are marked 
read only.

At least display some message and allow the user to cancel.

Nadim.
