Always analyse certain samples

[michaelweiser]

For EICAR-style testing it would be helpful if Peekaboo could be configured to always analyse certain samples, e.g. based on the sha256sum. This could be implemented by not saving the analysis result based on configuration directives. Alternatively, the known rule could be extended to allow configuration to ignore a certain sha256sum. Similarly, there could be an expression to query the known status, making the known rule superfluous.

Brainstorming:

1. not saving: Maybe a result extension in expressions such as '-> bad, nosave' and '-> ignore and not save' ?
2. the known rule and a corresponding expression could be an analyser, albeit one that doesn't actually analyse but produce a report of the cache contents instead.
