Fix issue #240: Multiple long option names / aliases (#349) 
* Fixes #240: Multiple long option names / aliases

* We now use a vector of long option names instead of a single name
* When specifying an option, you can provide multiple names separated by commas, at most one of which may have a length of 1 (not necessarily the first specified name). The length-1 name is the single-hyphen switch (the "short name").
* Hashing uses the first long name
* Option help currently only uses the first long name.

Support 'const char**' arguments in Options::parse (#250) 
`cxxopts` doesn't modify the contents of the argv strings. This changes
the parse function to take a reference to a `const char**`.

5da5d67111 Throw exception on invalid positional argument 
Fixes #169. It seems reasonable to throw an exception when an attempt is
made to parse into positional parameters that don't exist.

e725ea3084 Use unsigned type for integer digit 
Fixes #109. Although we always used numbers in the ASCII range, it was
in a `size_t`, leading to a warning about possible loss of data on some
compilers.

2ca68adeaf Fix positional arguments overload 
Fixes #83.

Adds an overload for positional arguments taking a
`std::initializer_list`. When using an `initializer_list` with one
argument, the function call is ambiguous matching both `std::string`
and `std::vector<std::string>`.

abe9ebd6b4 Fix handling of implicit values 
Fixes #84. Implicit values are not handled very well. For example:

    --foo false true
    --foo --bar

In the first, `false` is an argument to `--foo`, and then `true` is a
positional argument. In the second, because of the hyphen in `--bar`, `--foo`
is parsed with its implicit value. This seems inconsistent and unintuitive.

Better is that implicit values *never* consume the next parameter to be
completely consistent. This means that values with an implicit parameter
*must* be specified using the `--option=value` form.

8010e06952 Move parse result to an immutable object 
This is far from ideal, but it's the first step in moving the parse
result to an immutable object so that the parser can be reused.
