Custom Filter should show up in modules listing under "Input filters" with the rest of the Input filters.

Currently in my modules listing I have showing:

Filters

• Custom filter

Input filters

• Emogrifier
• Filter transliteration
• Flexifilter
• Markdown filter
• Pathologic
• SimpleWiki filter
• Summarizer
• Textile
• Typogrify
• Video Filter

Would Custom filter like to join the party?

Patch attached.
