e367fafa3d Return an error when parsing environment variables for values fails 
Currently cli silently (aside from IntSlice and Int64Slice which oddly
printed directly to the error stream) ignores failures that occur when
parsing environment variables for their value for flags that define
environment variables. Instead, we should propogate up the error to the
user.

This is accomplished in a backwards compatible manner by adding a new,
internal, interface which defines an applyWithError function that all
flags here define. In v2, when we can modify the interface, we can drop
this secondary interface and modify `Apply` to return an error.

0113f56d10 If no action is specified on the command or app, print the help documentation 
Rather than panic'ing or displaying an opaque error message about the
signature which is more confusing to the end user.

Fixes #562

3df4b71842 Backport no argument reordering as an option 
In the unreleased version 2, the argument reordering has been removed
(in f585ec7cb8) since it only worked if
all of the arguments appeared before all of the flags, but not if they
were intermixed which was of limited utility and caused some confusion.
This commit allows enabling of this future behavior via SkipArgReorder.

Ideally we'd support complete intermingling of flags and arguments, but
this is unlikely to happen until we switch flag parsers.

Fixes #515

When an if ends in a return the else is not required. golint
detects these conditions and found these.

042842b819 Remove CategorizedHelp from App and allow subcommands to have categories 
Just place all subcommands in categories, the default category will be
"" which will properly format the output (and group commands that have
no category).

Also allow subcommands to have categories.

Lastly, augment the test to check the output.
