Rewrite a function to make it work with 'bottle-pymysql'

[nikos]

Actually i kust found it has a directive:

dictrows: Whether or not to support dict-like access to row objects (default: True).

so i just did:

plugin = bottle_pymysql.Plugin( dbuser='nikos', dbpass='*****', dbname='counters', dictrows=False )

and now it works with indexes as integers not as strings.
