Added ext-searchbox (Ctrl+F) search/replace functionality and -workers (live syntax checkers) to the ace editor - a standalone hack.

if you don't need worker(s), modify line me-no-dev#446 of edit.htm .setUseWorker(!0) to (!1) (true to false) repack by do.bat and modify update_ace.bat 
Changes of src/WebAuthentication.cpp and minor updates of my SmartSwitch example
