Rename frameworks according to Cocoa convention

[jeanbarrossilva]

Apple adopts a naming convention for all of its system frameworks. Oddly, such convention is not documented officially. There is, however, an implicit understanding of the meaning of each suffix included in their names:

• Foundation
  Low-level, client-agnostic framework providing support for general programming concepts, such as string or floating-point manipulation. This category of frameworks does not introduce a new domain; rather, it implements those that are already established in the discipline and can be used by any domain specific to whichever applications.
• Core
  Similar to a foundation framework, differing in that it is specific to a domain of the operating system or application.
• Kit
  Provides client-specific implementations of the abstractions exposed by a core framework. E.g., a DatabaseProtocol may be defined in a DatabaseCore framework; a DatabaseKit framework may, then, expose an SQLDatabase implementation conforming to that protocol.
• UI
  Less common as system frameworks, the primary role of a UI framework in Deus is to expose views for rendering on the screen of the device on which the application is being run. These views are not tied to a given domain of the application, and may be referenced by multiple feature frameworks.
• Feature
  Even less common than UI frameworks as system frameworks, feature frameworks provide one or multiple user interfaces of a domain of the application, which may be rendered on the screen. This type of framework may use views defined in a UI framework, and differs from the latter in that it is specific to a domain.
