Can't use exclude option without explicit include

[jmuheim]

I don't want i18n-tasks to search for translations in abstract controllers and helpers like ApplicationHelper, where I have this method for example:

  def default_page_heading(options = {})
    t '.title', options
  end

I tried

search:
  exclude:
    - '*/application_helper.rb'

But this resulted in

josh@Macbuech:~/Documents/Work/MuheimWebdesign/base/src (features/accessibility *)$ i18n-tasks unused
/Users/josh/.rvm/gems/ruby-2.1.0@base/gems/i18n-tasks-0.7.13/lib/i18n/tasks/scanners/pattern_scanner.rb:14:in `scan': invalid byte sequence in UTF-8 (ArgumentError)

I had to explicitly also add include to make it work:

search:
  include:
    - '*.rb'
    - '*.html.*'
    - '*.text.*'

  exclude:
    - '*/application_helper.rb'

Is this expected behaviour?

Currently, setting exclude overrides the default exclude that is set to ["*.jpg", "*.png", "*.gif", "*.svg", "*.ico", "*.eot", "*.ttf", "*.woff", "*.woff2", "*.pdf"]. Perhaps exclude option should add to the default list instead of setting it, but then it would be impossible to un-exclude the default excludes with just configuration. What do you think?

I think one never needs to look through the default files, so one should simply add to the list.
