generate_needy_initializer does not allow a default value of false

[wezm]

I tried to define a field:

  needs required : Bool = false

but I get the error:

There was a problem expanding macro 'generate_needy_initializer'

Code in macro 'finished'

 1 | generate_needy_initializer
     ^
Called macro defined in lib/lucky/src/lucky/html_builder.cr:46:3

 46 | macro generate_needy_initializer

Which expanded to:

 > 15 |
 > 16 |
 > 17 |            @required : Bool,
                   ^
Error: argument must have a default value

It would appear that this line does not handle false:

lucky/src/lucky/html_builder.cr

Line 52 in 33606a6

{% has_default = declaration.value || declaration.value == nil %}

@jwoertink I have a few minutes this afternoon if you would like a PR for this. Just want to make sure no one else is working on it since it's a quickie:)

@bdtomlin Have at it! I'm definitely not working on a solution for this, so that'd be great.

This has been on my todo list for a long time so your help would be greatly appreciated @bdtomlin :D
