[#95981] Add a loading message into lines filter box.
#94986: Added proj4js to bower so we are able of transforming geometries (needed for the buffering solution for showing the area around stations, as the buffering operations only work ok on cartersian coordinates, and to have that we need to project the lat/lngs).
#94986: added support for handling min max and step values specified in the slider directive as attributes.
#94986: changes due modifications in angularSlider.js.
#94986: added CanvasLayer from https://code.google.com/p/google-maps-utility-library-v3/source/browse/#svn%2Ftrunk%2Fcanvaslayer for the canvas approach to showing areas around stations.
#94986: modifications of the loading indicator previously added by @moiarcsan
#94986: added proj4js and CanvasLayer libraries.
#94985: Added timers to the filter architecture.
#94985: improvements to filtering architecture so we prevent the erroneous removal of features that arent there and calling the clearing callback if not desired.
#94984: Improvements to checkbox styles.
#94986: Implemented buffer (using jsts and proj4 to avoid deformation) and canvas based approachs to the showing of walking areas around stations. The buffer solution is good in time terms, but it sometimes fail to include areas around some points in the buffer so its erroneous. The canvas based approach is the best developed so far, with drawing times in the range of 1~2 ms.
#94984: Updates to appengine (to require security) and gitignore files.

#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.
