Added :silence option to BenchmarkHelper#benchmark and turned log_level into a hash parameter and deprecated the old use [DHH]

Fixed that BenchmarkHelper should use controller.logger instead of @logger (which now apparently is gone)

Massive documentation update for all helpers (closes #8223, #8177, #8175, #8108, #7977, #7972, #7971, #7969) [jeremymcanally]

benchmark helper takes an optional log level, defaults to :info.  Chose symbols log levels rather than Logger::FOO constants for simplicity.  Added benchmark helper test suite.

Changed logging of SQL statements to use the DEBUG level instead of INFO. Added logging of the request URI in the benchmark statement (makes it easy to grep for slow actions). Changed the default logging level in config/environment.rb to INFO for production (so SQL statements won't be logged)
