Replaced parseQuery with getOptions and updated dependencies

[ManuelBauer]

Hello,

Because Webpack (or more precisely loader-utils) will remove the parseQuery() function with the next major version, I upgraded both the livescript-loader as well as the dependencies.

DeprecationWarning: loaderUtils.parseQuery() received a non-string value which can be problematic, see https://github.com/webpack/loader-utils/issues/56 parseQuery() will be replaced with getOptions() in the next major version of loader-utils.

Kind regards, Manuel
