Adding the config_manager as parameter for the abstract phone classes
Really adding $this as a parameter when preparing the phone specific in order to get infos like what is the brand, the family and more. I think that I will add a request type to know if we are in a TFTP or in a HTTP request
ga adding the requestType (http, tftp) in ConfigFile
Fix the name for the master_json templates
add a oui for cisco phones
So... several things in this commit:

- The Cisco spa5xx should be working (I tested on a 504g)
- Modified the way that is $settings is going through the abstract classes
  It was previously sent as a value and is now sent as a reference
- Added the Cisco spa5xx regex.
- Added a function to get the basic provisioner url. (shouldn't work with TFTP)
- Some other things
Timezone constants + restore constants.json name
del oui_list.json
