[issue #40] made action configurable so that a preview getmap url and a converter preselection mode may be set, however, these properties are not used yet
[issue #40] wizard is now initialised according to the currently supported converter preselection modes, preview url is set, too
[issue #40] changed from epsg code to crs instance to provide more flexibility/options to the wizard panels
[issue #40] using PureNewFeature instead of DefaultStyledFeature now so that the geometries created by the wizard behave exactly like the other 'creation modes'
[issue #40] implementation of all converter stubs including a new GeomFromWkbAsHexText converter and appropriate junit tests
[issue #40] the wizard supports text to geometry converters only as it takes text as input
[issue #40] the change listener is more sensitive now and thus the enter data visual panel editor pane does not move the curser to the end of the document anymore if anything is entered in the middle of the document, disabled file open controls as the first iteration will most likely not have this feature
[issue #40] newly created feature has to be on hold to be consistent with other create-new-geometry-actions
[issue #40] proper preview map initialisation, except that the value read from properties is not used yet for testing purposes
[issue #40] proper selected converter memory for the first panel, additionally selected converter is now shown in enter data panel
[issue #40] prepared enter data panel to be able to detected the format of the data so that it can automatically selected an appropriate converter
[issue #40] icon for the wizard action
