Skins system on merkalt sites.

Each standalone domain package of files contains /skins/ folder. Each folder in skins are used to store template files, css and images. Usually there are the next folders - 

  * global - this folder contains files which are generic for all instances. It contains common images, main css file, templates which are not different for instances like motifs menus, tabs menus, etc. 
  * local folders (eg. - Merkalt, Fargenavnelapper, Idband) - this folders contains specific images, css file, templates for current instance.  
 If instance uses tabs setup then there is main skin (Merkalt for merkalt.no). Skins folders names are equal to tab headers. The system allows to create different local folders for each instance (eg.- Fargenavnelapper will serve Fargenavnelapper tab on merkalt.no and FargeStandlone will serve merkalt.no/fargenavnelapper)
  * skins folders (eg. MerkaltA, MerkaltB) this folders content is used if [[merkalt::Skintracker]] is enabled.    

how the necessary template is loaded

  - if [[merkalt::Skintracker]] is enabled and template is existing in skin folder it is loaded, otherwise
  - if template is existing in local folder it is loaded, otherwise
  - if template is existing in global folder it is loaded, otherwise
  - template is ignored
