QgsFilePicker and QgsExternalResource: new file picker widget and edi…
…tor widget for improved file name widget * QgsFilePicker is intended to be used across whole QGIS application for file picking * right now it supports only single file/folder selection * it has advanced support of relative path * QgsExternalRessourceWidget is the pending editor widget which integrates a photo/web viewer * it can be properly accessible from the API and custom widgets * new class to avoid duplicating code for legacy support * old widgets will be removed from QGIS 3 (users will be invited to use the new widget in the config dialog)
