Insert Blocks in CCK text fields not working

Hi mlsamuelson - first of all, this is a great module - although apparently hardly any updates have been done on version 5.x.

Anyway, this is my first attempt to actively contribute to a module as I've fixed an issue for my own purpose and wanted to share this with others who might need the functionality - so please advice if my contributed patch file doesn't meets all the formating requirements - any comments and hints would be highly appreciated if I need to modify the patch to make it applicable for others (I use Eclipse PDT on a windows platform).

So, here's the issue: If you use this module in pages with CCK (text) fields the block tags did not get rendered. This is because you use the insert_block_nodeapi ... maybe you need to do this for some reason I don't know ...

My solution actually uses "process" case of "op" to directly call the substitute function - thus it works for all fields and is not only applied to the content variable (actually the original version just works for body and teaser of the content variable).

Some designers (including me - and that's how I discovered the issue) don't use the content variable in their templates but rather use directly field values (e.g. content['body']['#value']) especially since I have several other CCK fields that need to be printed at different positions in my pages. These values were not updated correctly by the filter ...

I don't know if this is of any help for 6.x - however, I hope this will help someone else, who still works with 5.x versions of modules and has run into a similar issue.

Thanks again for providing this easy to use module - it allows me to do things much simpler and yet with more individual formatting possibilites than panels would do!

Cheers!
