3264 refactored admin page functions to work with newer syntax, they are working again.

quoting closed error because it is extremely related:

Almost none of the admin functions work as they were initially intended, mainly:

• search of total number of brews always returns a 503 (timeout)
• search for deletable brews is limited to aprox 0.008% of the current brews database, which is incredibly low, and higher searchess also return 503 (timeout)
• Not as important but brew by Id should return more info like creation date (relevant 2 days ago to figure out a 2k page brew was 8 days old)

We also might want to include other functions to get some data, like charting brews by page number, or users by brew number...
