CONTRIBUTING.md

I'm having an issue:

1. Search issues, maybe your issue is already solved
2. Before submitting an issue make sure it's only related to Meteor-Files package
3. If your issue is not solved:
   • Give an expressive description of what is went wrong
   • Version of ostrio:autoform-files and ostrio:files you're experiencing this issue
   • Version of Meteor you're experiencing this issue
   • Is it Client or Server issue?
   • Post Client and/or Server logs with enabled debug option, you can enable "debug" mode in Constructor

I have a suggestion:

1. PRs are always welcome - send a PR
2. If you're can not send a PR for some reason:
   • Create a new issue ticket
   • Describe your feature / request
   • How you going to use it? Give a usage example(s)

Documentation is missing something or incorrect (have typos, etc.):

1. PRs are always welcome - send a PR
2. If you're can not send a PR to docs for some reason:
