deprecate signal

I consider this tag to be ambiguous and this has been used on different stuff, such as:

• post #1059322 - should've been sound wave instead,
• post #2126052 - railroad signal,
• post #4884702 - I see nothing like a signal there. But some kind of device that scans transit fare card. We already have card reader
