In SkCommandLineFlags, if the client sets a default value
of multiple arguments (e.g. "arg0 arg1 ..."), set
the actual defaults to all of those arguments separately
(i.e. an array with [0] == "arg0", [1] == "arg1", ...),
rather than as one string (i.e. [0] == "arg0 arg1 ...").
Remove the hack that worked around this bug.
Also move the increasingly complicated implementation of
SkFlagInfo::CreateStringFlag into the cpp file.

Two dashes are used for flags with multiple characters, and one
dash is used for flags with single characters.
In GM, changed '-wp' to '-p' (the command to choose a directory
for writing SKPs) to fit with the convention.
In render_pictures and bench_pictures, changed the flag for
read and write path to have full names (which are consistent)
and use the old single character names as their shortcuts.
SkCommandLineFlags: Updated the documentation, and only allow
-h or --help for help (again, to match the convention).
Also enforce the single character limit for the short name, and
require the full name to be at least two characters.
Provide full names for skhello.
