the only lists I know of are in the source code... I don't know of any
docs that explain them, unfortunately.

the list of match rules are in camel-folder-search.c in the 'builtins'
table.

the list of filter actions are listed in camel-filter-driver.c in a
table called 'symbols'

as far as what the arguments are, I don't recall off the top of my head
for each one, so you'll have to read the callback functions for each of
those to figure it out.

changing the xml file will make them appear in the list and will work.
