blogDir allows []

[rainecheck]

While removing the blog from a site, I noticed that there was some inconsistent behaviour with the declaration of blogDir:

Syntax	Returns	Result
blogDir: ""	Error	[ERROR] ValidationError: "blogDir" is not allowed to be empty
blogDir: null	Error	[ERROR] ValidationError: "blogDir" must be one of [string, array]
// blogDir: ""	Warning	Warn: blogDir doesn't exist: "{snip}/blog".
blogDir: [""]	Error	[ERROR] ValidationError: "blogDir[0]" is not allowed to be empty
blogDir: [null]	Error	[ERROR] ValidationError: "blogDir[0]" must be a string
blogDir: []	Success	No issues, works fine.

Allowing an empty array but not allowing an empty string or a null string seems like it's not intended.

The use case for me here is to declare indexBlog: false, but thought I'd raise this an a minor issue.

Took me a while to find the cause of the message

Warn: `blogDir` doesn't exist: "..."

Google search doesn't index this page somehow.

The solution is given above: set indexBlog: false. This option comes from the theme options

I think it's better to show it comes from this package, so developers can find relevant config.
