#144 Defining Filters

[Patrick Schönbach]

It should be possible to define filters, globally, per folder,
and per feed, that allow to totally eliminate items based
on regular expressions.

For example, it should be possible to eliminate items
where the headline starts with "ADV:.*".

I would love to have the ability to apply my own regex
filters to any feed (globally, per folder, per feed, etc).

Not just to filter out entire items, but also change the
item as desired.

Maybe I'd like resize images:
s/<img/<img height=200 width=200/g;

Or filter out certain words:
s/fiddlesticks/censored/g;

Or bring attention to things:
s/(SourceForge)/\1/g;

Add a coral link to the site:
s/.([net|com|org])/.\1.nyud.net:8090/g;
(I know that's simplistically wrong. you get the point)
