config+url: add support for user-defined regex patterns

Browse source 
Users can now define their own regex patterns, and use them via key
bindings:

    [regex:foo]
    regex=foo(bar)?
    launch=path-to-script-or-application {match}

    [key-bindings]
    regex-launch=[foo] Control+Shift+q
    regex-copy=[foo] Control+Mod1+Shift+q

That is, add a section called 'regex:', followed by an
identifier. Define a regex and a launcher command line.

Add a key-binding, regex-launch and/or regex-copy (similar to
show-urls-launch and show-urls-copy), and connect them to the regex
with the "[regex-name]" syntax (similar to how the pipe-* bindings
work).
