Currently webscenario items and their keys in database are containing name of webscenario and name of webstep.
This means that each time, webscenario or it's step's name is updated, we need to update all related items (this is a heavy update, especially if inheritance is taken into account).

This can be avoided, if we will introduce macros for webscenario name and webstep name and replace all webitem names and keys with strings, containing these macros.
