Anthony Fok 4745f1fd64 In execute(), check if command is Runnable() 
A corner case exists where c.Runnable() is not checked
before c.Run() is called, thus a nil c.Run is executed
leading to "panic: runtime error: invalid memory address
or nil pointer dereference".

This patch adds an extra c.Runnable() check in execute()
to catch that corner case.

Fixes #37.

Clayton Coleman 9b6c92647a When no subcommands are registered, omit command help output 
For a single root command with a Run method, the help output still
contains 'help [command]' as a subcommand (because Help is always
added). Since the only subcommand would be 'help', the help is better
off omitted.

This change allows a command to be used both as a subcommand
or a root command without having to define a custom help that elides
the help command when no subcommands are added.  Instead, the default
help command is only added when subcommands are present.

tummychow 667c348dbd Test behavior for subcommand with same name as root command 
If, for some reason, you have an application with some name "foo", and your
app has a subcommand "foo", cobra should behave properly when you call
"foo foo", and it should also behave if you call "foo f".

These changes verify both of these cases and ensure cobra responds properly.

tummychow f4c075f8f8 Add command name prefix matching 
A command can now be invoked with a prefix of its own name, assuming that
prefix is unambiguous (ie it isn't also a prefix of any sibling command's
name).
