Make it not throwing errors on vibe's CLI options

Bug was caused by mixing vibe's getOption and std.getopt so making it
use only vibe's getOption solved this.
Merge branch 'master' of https://github.com/rikkimax/Cmsed
Merge pull request #3 from katyukha/master

fixed bug. When run program based on cmsed and place vibe's option like --vv error was thrown
