api: rewrite scrollframe template

Browse Source 
Replaced the scroll indicators by a small scrollbar indicator.
By that also removed tons of superfluous textures and reduced the padding.
This change should be still compatible to the old implementation.
Tested Addonmenu and the pfQuest Browser and it still seem to work properly.
