MdBook Variables preprocessor

A simple preprocessor for mdbook, that look for variable in double brackets and replace with some value that come from the book.toml

Example

SimpleFile.md:

## something

a contentent with a variable {{name}} 

book.toml

#... all the basic detail first and then:

[preprocessor.variables.variables]
name= "my wonderful name"

It does support looking for variable values in the environment variables behind a flag

Toml configured variable right now take precedence on environment variables.

[preprocessor.variables]
use_env = true

[preprocessor.variables.variables]
other_variabled_not_in_env= "value"

The implementation got a lot of inspiration and code from the mdbook links preprocessor an mdbook-plantuml.
