Clean global scope in all controllers.

[NitayRabi]

Overview of the problem

We have several functions declared globally in controller files.
This can create issues hard to anticipate and solve.

Description

1. We need to move all functions into scope.
   
   
2. We need to make sure the functions aren't used in any other file (if so, we should create an AngularJS service to be shared between the controllers)
3. Sanity after the cleanup - check most screens and buttons don't raise exceptions related to missing functions.

Expected behavior

Functions should be scoped

Actual behavior

Functions are declared outside of AngularJS's controllers call back

[galnitsan]

function moved inside controllers.
suitable names were named for these functions.
the "old" names of functions were changed to the "new" names in all functions calls.
2 new services were create (factory) - (camps/suppliers).
camps/suppliers services were injected to relevant controllers.
camps/suppliers services were declared in layout.jade (under "spark scripts").

still 1 issue in suppliers edit page.
