[Feature Request] Flexible directory structure

[etki]

Hi!

Currently Zephir forces fixed directory structure that may lead to some perfectionist starvation:

• Zephir forces to replicate namespace structure as directories, forcing developer to have extra complexity in their project and preventing from placing .zep files right next to their PHP counterparts
• Zephir forces sources location next to config.json (while most projects store their configuration in root, and sources under src/lib/name it directory)
• Zephir places ext directory next to sources, which is usually unwanted (usually build directory stands aside from project sources, and it's name may vary)

So i suggest to add paths configuration option with following children:

• sources: tells Zephir where source files are located. If set, it is implied that directory specified in sources contains namespace specified in namespace, so if i have namespace AmaTeam\Utilities, paths.sources equal to src and file src/Strings.zep, class FQCN would be AmaTeam\Utilities\Strings. If not set, Zephir continues to act as now.
• build: tells Zephir where to execute the build, defaulting to ext relative to config.json
• logs: self-explanatory
• tmp: self-explanatory

I don't understand. You want to mix .zep files in with .php? What is the use case for that?
