Fix a bug - the http port was not considered when rendering the WMS map, leading to a connection error
Redo Value Classification UIs

A lot of code was refactored and pushed up to PnlAbstractTableAnalysis
in order to ensure consistency between Value and Interval
Classifications. This also removes a lot of redundancy.

Fix WMS connection error bug

The http port was not considered when rendering the WMS map, leading to a connection error when the source is loaded in the TOC.
Refactor: Consolidate onVertex/onCentroid methods

Previously there were three different implementations of the
onVertex/onCentroid panel. I consolidate all three of them into one in
this helper class.

Note: "Place symbol on" will be translated by "Placer le symbole sur".
Then there should be plenty of room for the radio buttons.
