This commit is a little step for 2600hz but should be a big step for Andrew.

- Renaming the index.php (process.php)
- Seperating 2600hz stuffs from the rest
- First step towards the TFTP support
- Everything should is more modular
- The entry point is easier to read, more simple.
- Creating the config_generators stuff.
- Some changes in the autoload/boostrap
- Modifying the set_config_file parameter. It is now the target file name and not the uri.
	This will allow us to use this function with a TFTP server
- Adding some settings line ("config_manager" and "server_type")
- Refactoring the brand_data.json files

The next step should be to restore the family_data.json for the TFTP stuff.
We will then be able to specify the target config files to generate.
