select (one/multiple) could not chose from a list of objects, since DOM requires string ids.
Solved by adding index formatter, which exposed incorrect handling of formatters in select
widgets.
camelcase is used for other angular functions and forEach is also
used by EcmaScript standard.
- rename the internal as well as the external function name
- tweak the implementation of the function so that it doesn't
clober it self when we extend the angular object with an
object that has a forEach property equal to this forEach function
Closes#85
