Support for wildcards / regexp

[blueyed]

It would be great to match against simple glob patterns like f*o when filtering the list, which would match foo.

I am not sure, if regular expressions are useful to have enabled by default (requiring to use .* instead of just *). Maybe this could be switched similar to case sensitivity.

One of the things that kept me from supporting this is speed.
With Clerk we already notice that the utf8 case-insensitive matching can be slow for large lists (30k items).

Is there a ready to use fast glob matching library (glib has g_pattern_spec_* but no idea how fast this is.)

Maybe it'll be cool to add possibility to enable glob patterns for different show modes? Patterns will be very useful for window or ssh mode and more often then not both of them have very small lists.

[DaveDavenport]

@f1xmAn glob matching has been added.

@DaveDavenport thank you!

@DaveDavenport
Using -glob does not match the WM_CLASS column anymore, and should probably not be bound to the beginning of the string (i.e. "fox" should also match "Firefox").

[DaveDavenport]

yeah, I only append a * should probably prepend one too.
In fields it matches nothing has changed.

In fields it matches nothing has changed.

Does not match '*Fire' in the first col for "Firefox".

[DaveDavenport]
