Subject: [PATCH] Update: Add support for +E/++error, change '+q' to '+Q', and
 fix some past tense words.

Selecting a quiet mode that still prints errors is very helpful in embedded fakefiles inside of controller rules.

I noticed that almost all of the verbosity related parameters are upper case except for the "quiet" parameter.
Change the "quiet" parameter from "+q" to "+Q".

I noticed some words in the past tense.
The goal is to use present tense.
Using past tense a habit I hope to get out of when programming.
