workspace view colors based upon variable scope (derived from Dan's patch #8013)
* resource-manager.cc/.h(storage_class_names): function returning scope names
(storage_class_colors): function returning default colors for scopes
(storage_class_chars): function returning the ident. characters of the scopes
* color-picker.cc(constructor): prevent focus for the colored pushbutton
* settings-dialog.cc/.h(read_workspace_colors): function reading the colors from
the setitngs and creating a table with color-pickers in the settings dialog
(write_wirkspace_colors): function getting the states of the color-pickers
and writing them into the settings files
* settings-dialog.cc(constructor): call read_workspace_colors
(write_changed_settings): call write_workspace_colors
* settings-dialog.ui: new tab for workspace settings with a box for the colors
* workspace_model.cc/.h(notice_settings): reading colors from the settings
* workspace-model.cc(constructor): initialize list of colors
(data): reorganize determining the appropriate data and take background
color role into consideration
* workspace-model.h(storage_class_color): returns the color for a specific scope
* workspace-view.cc/.h(notice_settings): create tool tip with color key
(setModel): not inline anymore, actual model is stored in _model
