Update special://profile before attempting to load the profile's guisettings.xml file.
When ProfilesManager::m_currentProfile is changed the special://profile path must be updated as well.
Added SetCurrentProfileId() function for manipulating m_currentProfile. Replaced all occurances of direct manipulation by using this function. This makes sure that the special://profile path is updated as well when updating the current profile id.
Since SetCurrentProfileId() is called in ProfilesManager::Load(), the special://profile path is now automatically set which made it obsolete in CApplication::Create().
Remove setting of special://profile path from OnSettingsLoading(); special://profile path is already set to the correct path when the settings are being loaded.
