Provide a rich syntax language or directives for spam keywords

[engram-design]

Currently defining spam keywords are incredibly basic, and the most common issue is that they partially match. So if you wanted to catch the word ass and a user provides assistance, brass, grasshopper (and of course many more) are going to match due to the word being at the start, middle or end of a string.

Now we could provide settings to match whole words or not, but a more rich syntax would be ideal to define rules per-line in text. For example, you might want to make some rules like:

• Exclude the word ass as a whole word
• Exclude the word hamper anywhere in the text
• Exclude words starting with, or ending with certain text

I'll see what options are out there as well, to build off ideas from others! It may very well be the case that we're over-complicating things and just need a whole-word or occurrence matching setting for keywords.
