String is automatically casted to number

[in2lag]

Current behaviour:

• if you run i.e. gulp build --production --version="6888e97"
• output of require('gulp-util').env.version is 6.888e+100

Expected behaviour:

• If argument is passed in quotes, argument is still string

Use a different argument parser.
