#187 Change boolean option parsing

[beci]

change: modified boolean option parsing, don't parse the next value for boolean options.

Prevent the annoying prevous behavior when parsing a boolean option followed by variadic arguments parsed the first followed as value for option instead of true and parst the variadic arguments from the second element only. Like --verbose first second was parsed where the verbose value was first instead true and the followed array is only [second] instead [first, second].

In order to achieve this the shouldTakeNextAsValue function extracted from handleConcatenatedOpts and use it in handleOptWithoutValue as well. I know this is not the optimal implementation, but I prefered as little modifications as possible. Also, need to change description, because the Option synopsis desciprion is not valid anymore:

-f, --file means the option can be provided either by its short notation -f or by its long notation --file. You don't have to repeat the placeholder twice in that case.

Also fixed the rawOptions, where the inverted values was stored for negative flags.
