bin/map: Fixed bug introduced in r1718 where the row # would not be incremented if i < start, causing an semi-infinite loop that only ended when the input rows were exhausted. process_rows(): Added optional rows_start parameter to use if the input rows already have the pre-start rows skipped.

input.Makefile: Sources: cat: Changed Usage message to use "--silent" make option

input.Makefile: Sources: cat: Added Usage message with instructions for removing echoed make commands

run_*query(): Fixed bug where INSERTs, etc. were cached by making callers (such as select()) explicitly turn on caching. DbConn.run_query(): Fixed bug where cur.mogrify() was not supported under MySQL by making the cache key a tuple of the unmogrified query and its params instead of the mogrified string query. CacheCursor: Store attributes of the original cursor that we use, such as query and rowcount.

sql.py: Made row() and value() cache the result by fetching all rows before returning the first row

iters.py: Added func_iter() and consume_iter()

sql.py: Cache the results of queries (when all rows are read)

Proxy.py: Fixed infinite recursion bug by removing setattr() (which prevents the class and subclasses from storing instance variables using "self." syntax)

sql.py: DbConn: Added run_query(). run_raw_query(): Use new DbConn.run_query().

Added Proxy.py
