Minor typos and inconsistencies in help output

[arcrose]

Reading through the help strings produced by MIG running in Docker, I came across some typos and inconsistencies that are practically inconsequential. I wanted to open an issue for them so that I might be able to address them as I familiarize myself with the codebase.

1. In the main mig --help output, there is a typo in "config"

-c path to an alternative confiig file. If not set, use ~/.migrc

Specifically,

confiig

2. The examples showing how to use the -t flag are a bit inconsistent (perhaps intentionally?)

-t target to launch the action on. A target must be specified.
examples:
* linux agents: -t "queueloc LIKE 'linux.%'"
* agents named mysql: -t "name like '%mysql%'"

Here, the second example has LIKE in lowercase.

3. In the description of the -size flag accepted by the file module

-size - match files with a size smaller or greater that

Specifically,

greater that

4. In the description of the -macroal flag accepted by the file module

-macroal - by default, a 'content' regex only need to match one line of a file
to return a match. With the 'macroal' option set, all line of a file

Specifically,

all line
