Alpha 1-7

This release includes some new features:

• A new API:
  • run now takes a string with the function name and a variadic list of function parameters and returns a serial object representing the result of the function call
    • dispatch and run_callback have thusly also been changed to accommodate for this
  • A new function package creates a serial object representing a function call
    • This object can then be passed to run_object (probably over a connection to a server)
  • run_object and run_string are introduced to dispatch based on a serial object and string representation of a serial object, respectively
  • run functions and package can now be called asynchronously using async_run and async_package
• Bug fix for passing a character array as a parameter
• Ability to generate doxygen documents
