Fixed non-working Spanish validator translation

This translation contains translation keys from the ZF1 validators *NOT* the ZF2 ones. This effectively renders them useless since most of the ZF2 translation keys have changed. 

I updated all the translations so that they work with ZF2 and also corrected a few grammatical errors and typos.
Added resources/languages/id for Indonesian translation
AbstractWord instead of Word
ID revision date
change 'dengan' with 'dari' for comparisan
change 'file' to 'berkas'
remove surpluss "pola"
change "error" with "galat"
added missing "yang" and "untuk"
Fixes #4670
refactor code
added testRemoveMethodInsensitive
