* Added a new macro SNAME() that constructs and caches a local stringname. * Subsequent usages use the cached version. * Since these use a global static variable, a second refcounter of static usages need to be kept for cleanup time. * Replaced all theme usages by this new macro. * Replace all signal emission usages by this new macro. * Replace all call_deferred usages by this new macro. This is part of ongoing work to optimize GUI and the editor.
