v0.5.0

• Changed module name from StructBuilder to Buildable. Please update your linked package in the Xcode settings and update the import statements accordingly.
• Changed behaviour when generating struct builder. When a struct initialiser exists @Buildable now uses the first/top initialiser instead of guessing what the initialiser could look like from the struct member variables
• Fixed an issue where generating a struct builder would fail when a constant let myConstant = "" would be part of the struct. An initialised constant can not be part of a member-wise initialiser.
