defaults MacroPath (SF#384)

Hello,

At the LPS they are using sardana to control their diffractometer. The Sardana process run as the logged users in order to save the data with the right uid:gid. Now they want to write macros as user but also as administrator of the system in order to prevent user from modifying these macros.

If I look at the msmacromanager, it seems that the DEFAULT_MACRO_DIRECTORIES = os.path.join(_BASE_DIR, 'macros'),

path is is in fact the installed path of Sardana/macro directory. They know that the MacroPath property can be added to the macroserver device in order to add dedicated path to the MAcroserver, BUT, each time they need to log as a different user, they need to ad one more data path.

It would be great if by default Sardana should follow the xdg standards in order to find its macros. This would help a lot.

thanks

Vincent and Fred
