add option -i(ignore) to misspell linter

[hgsgtk]

I wanted to use misspell linter, however to use misspell we have to set ignore option -i.
Do you have a plan to add ignore option? Or Can I challenge to add ignore option to golangci-lint?

  -i string
    	ignore the following corrections, comma separated

1. Version of golangci-lint: golangci-lint --version (or git commit if you don't use binary distribution)
   7b2421d

2. Config file: cat .golangci.yml

linters-settings:
  govet:
    check-shadowing: false
  golint:
    min-confidence: 0
  gocyclo:
    min-complexity: 30
  maligned:
    suggest-new: true

linters:
  enable-all: true
  disable:
    - gochecknoglobals
    - dupl
    - lll
    - goconst
    - depguard
    - goimports
    - misspell
    - scopelint
    - gosec

3. Go environment: go version && go env
   go version go1.11 darwin/amd64
4. Verbose output of running: golangci-lint run -v
