Rename all_enty occurrences which only depend on emiTe

[spahrm]

This PR is the first part of the refactoring of the all_enty from Remind. Replacing this set step by step improves readability and makes it more clear which part of the set is actually used in equations, parameters and variables.
In the first step a report was generated which contains all variables,parameters and equations, depending on all_enty, but actually only in a subset form from the set emiTe. This report can be found here:
emiTeReport.csv

Afterwards all occurrences of these variables where located in the remind folder and replaced with emiTe instead of all_enty. After each replacement a testOneRegi run was performed to check if simulation results alter. After all possible variables were renamed, SSP and policy runs where executed to check the simulation results even more carefully.
There are changes between the develop and the emiTe runs, please review them carefully.
