Feature request: allow a {*} for all symbols to avoid spammers rotating symbols in ads

[SunTzuTech1]

Describe the problem

Spammers are rotating the symbols they use in ads, so I block "{diamond} WTS SP Boost", and next they send "{star} WTS SP Boost" which is seen. {*} would represent any of the symbols, and block this obnoxious behavior by spammers.

Would be nice not to have to explicitly call out symbol changes by the spammers

What steps will reproduce the problem?

1. block "{diamond} WTS SP Boost"
2. spammer then changes to "{star} WTS SP Boost

What version of the addon are you using? (Stating 'latest' is not useful)

v9.2.3

Do you have an error log of what happened?

no error, it's a request for enchancement [and will make badboy, even badder... ;-) ]

Any additional information? (example: WoW language if not English)

another recommendation

1. have an "ignore" symbols option, so that it doesn't matter what symbols they use

2. keyword list [lfm swp trash]
   anything that matches this, gets dumped. should work well with the above "ignore symbols"

3. collapse whitespace between tokens. so that
   "lfm swp trash" is the same as
   "lfm _ swp _ trash" (see that _ is really a ' ', but this editor collapsed the white space....lol)
