Improve the functions that match Min. Edu. data with DNE data

[cmdelatorre]

The current script to match the DNE schools with the data from the Min. Edu. is really basic. A lot of things can be tryied in order to improve the number of schools found in the Min. Educ. data.

For example, when checking if a given school name or address corresponds to other we have cases like this:

• DNE: ESC MARIANO MORENO, SANTA ROSA ESQ SANTA FE,
• Min. Edu.: ESCUELA MARIANO MORENO, SANTA ROSA 1299 ALBERDI Atras del edificio Central de Policia

Or:

• DNE: ESC ERNESTO BANCALARI, MONTERROSO 4597 B° ARTIGAS
• Min. Edu.: ESCUELA ERNESTO BANCALARI, MONTERROSO 4597 GENERAL ARTIGAS

Blacklisting words like "ESC" and "ESCUELA" would help to improve the matches.
