templater: adjust binding strength of '%' and '|' operators (BC)
This makes 'foo|bar%baz' parsed as '(foo|bar)%baz', not 'foo|(bar%baz)'.
Perhaps it was a mistake that '%' preceded '|'. Both '|' and '%' can be
considered a kind of function application, and '|' is more like a '.' operator
seen in OO languages. So IMHO '|' should have the same (or higher) binding as
'%'.
The BC breakage should be minimal since both '|' and '%' operators have
strict requirements for their operands and 'foo|bar%baz' was invalid:
- right-hand side of '|' must be a symbol
- left-hand side of '%' must be a dict or list
- right-hand side of '%' must be a string or symbol
