Option to ignore .d.ts files

[louy]

In my projects all .d.ts files are automatically generated and I don't want to lint them. This means that I can't just `tslint **.ts" because that'd include them as well. What I end up doing is

find -name *.ts . -echo0 | grep -i .d.ts | grep -i node_modules | xargs tslint

which is really annoying.

I can submit a PR for this if #827 gets merged.

@adidahiya What do you think?
Anyway it's as simple as pushing "**/*.d.ts" to GLOB_IGNORE in #857.
An --ignore option would do as well.

I'd like a way to do this in config. Perhaps an ignore block in tslint.json?

For instance, Atom insists on linting the .d.ts files in my typings directory, which rarely conform to my tslint config because they come from the wider world. Also those files can be enormous (react.d.ts is 2200+ lines) so it'd probably shave off some loading time if they weren't linted.

#1006 added the ability to specify exclude patterns via CLI
When linting with --project *.d.ts files are excluded.
