#172613 by sun, smk-ka: Changed Inline API to use hook_filter() instead of hook_nodeapi(), solving many issues around previews and missing node ids in macro tags.

- Added support for custom inline tag names.
- Added support for multiple parameter instances (f.e. for gmap).
- Added support for parameter default values.
- Fixed invocation for extended parameter validation.
- Added support for altering macros (f.e. for ex. inline[_upload]).
- Added support to build/generate macros.
- Added CCK support.
- Updated help texts.
- Changed operation 'args' to Forms API style to support a basic Inline API
  widget for each Inline implementation.

inline_upload:
- Fixed node previews.
- Fixed numeric file references.
- Re-enabled support for Inline auto-add.
- Removed obsolete functions from Inline v1.
