feat(tasks): enable excluding tags from view

 Dots and slashes can be repeated to move to parent tasks.
 
 - `:[IND][PROP]` - add property column PROP at IND or end, if it already exists remove property column PROP or IND (1-indexed)
-- `::[PROP]` - Sort by property PROP
+- `::[PROP]` - Sort by property PROP (multiple space-separated values allowed)
 - `([TIME]` - insert timetracking with the specified offset in minutes (empty: list tracked times)
 - `)[TIME]` - stop timetracking with the specified offset in minutes - convenience helper to move to root (empty: stop now)
 - `>[TEXT]` - complete active task and move to parent, with optional state description
