Update code to use latest datajoint conventions

[ecobost]

For instance:

• Table() & key -> Table & key
• Table().fetch/insert -> Table.fetch.insert
• def make_tuples -> def make
• in definition string: (renamed_col) -> Table(col) -> -> Table.proj(renamed_col='col')
• in Part tables: ->NameOfMasterTable -> -> master
• use the iterator ability of tables: for row in Table.fetch() -> for row in Table (this may only work if using proj, not sure).
