Clean names of master data

[maurolepore]

@gonzalezeb,

The master allotemp_main.csv data has names that are difficult to work with. Can you change its names to not have "(" or ")" or spaces? Ideally all names should start with a letter and include only letters, numbers and "_", not "." nor spaces.

If this is not possible let's discuss.

No more spaces, parenthesis, all in small letters, removed one duplicated column..
