[Cpptool-develop] Modified RenameTempRefactoring interface...

[Baptiste L. <gai...@fr...>]

    I modified the interface so that the refactoring is done in two steps:

    - on construction, check selection and source validity and collect datas
to prepare the refactoring (locale variable node and occurrences)
    - on apply, just make the necessary transformation with the specified
parameter.

    Splitting the refactoring this away allow us to provide some information
in the user interface (e.g. old locale variable name).
