uninitialized constant Brakeman::RenderHelper

I have an error when launch brakeman :

```

```

After this, I discovered that the way to require processors in lib/processor.rb is 

```
Dir.glob("#{File.expand_path(File.dirname(__FILE__))}/processors/*.rb")
```

and which cause my issue, because "render_helper" seems not required in some files which include it, so for now i just add 

```
require 'brakeman/processors/lib/render_helper'
```
to lib/brakeman/processors/slim_template_processor.rb

for a temperate fix, maybe there are some better ways to require it ?
