CodeRay's coderay_bold_every can't be set to false

[simonvanderveldt]

Coderay's coderay_bold_every can be set to false or to an integer, see CodeRay's numbering.rb (line 35).

But because the type is set to Integer in kramdown's options.rb (line 326) it's not possible to set it to false.

Changing the integer in the define in kramdown's options.rb to an Object makes it work

define(:coderay_bold_every, Object, 10, <<EOF) do |val|
Defines how often a line number should be made bold

Default: 10
Used by: HTML converter
EOF
    val
end

This obviously uses a block that doesn't do any validation. I'm not fully proficient in Ruby, so I don't really know which kind of validation one should do.
I guess a check on val == false and Integer === val should be enough?

Thanks! I have updated the option to also allow false as value.
