New timestamp format.

Logger timestamp format 2011-02-22 04:15:20 with letter %T
Unnecessary error object logging removed.

It was writing an error object to the log file with all
html formatting, what is wrong.

New test t/04_static_file/02_dir_traversal.t

Test a number of paths to ensure that directory traversal attempts do not
succeed, and result in a 404.
Condense test to just check no file response for bad URLs.

Just check that we didn't get a file response.

Previous approach was no good as Dancer::Test::_get_file_response() returns
undef if there was no file to serve up.
Fix path normalisation in Dancer::FileUtils

This solves a potential directory traversal issue allowing static files to be
served from a level above the public/ dir, which could be dangerous.

Thanks to Vladimir Lettiev aka crux for reporting this regression.

	CHANGES
Set 'Server' response header as well as 'X-Powered-By'.

Makes sense for Dancer to be shown as the server, if it is.  If the app is
running behind another webserver running as a proxy (Nginx etc), then this won't
be visible unless the server has been configured to pass on that header.

Makes sense for use of Dancer to be visible - who knows, we might even show up
on www.netcraft.com eventually :)
Link to Dancer::Logger in debug/warning/error docs.

Also, provide example for warning, to be consistent with debug & error.
Linkage in Dancer::Cookbook to keyword docs.

It makes sense for keywords mentioned in the cookbook to link to the canonical
documentation of the keyword in Dancer.pm for further info.

This came to mind during a discussion with tylerdu on IRC, so thanks to him for
spurring me to do that :)

(There's also a couple of minor typo/wording fixes, too.)
