#94986: Improved layout of the slider and added color badges to the lines entries so the user is able to recognize the line in the map.
#94985: Added skipFilter parameter to the add, update, and remove methods of the toolFilter so if we are doing many single operation in a tool we don't incur in a big overhead due to over filtering. Also, fixed substraction of features.
#94986: fixed a problem in which the filtering geometry associated to a station that appears in two lines remained in the filter (whitout the possibliity of removal unless using the global clearall tool) because it was being added one time for each line. We now remove the station geometry before recreating it.
