[PD] external search precedence

[Hans-Christoph Steiner]

Yes, that's right.  You can see more detail in this paper on libraries
http://at.or.at/hans/Let%27s_Make_Libraries_-_PdCon3.pdf

Specifically:

4.3 Search order is also important
In an effort to make the library format as simple as possi-
ble, it is also necessary to consider the order that the library
paths are searched for a given name. Currently, Pd searches
each possible name through all of the paths before it tries
the next type. This means it is not possible to use the name
that binary ob ject has if that binary is included anywhere in
the search path. The binary always takes precedence, even
if someone sticks a Pd patch with that name in the same
folder as the pro ject (e.g. ".") While is it a good idea to
avoid name clashes, it is confusing if you create a patch with
a name, and then something else is loaded from the path.
With more and more Pd libraries being written in Pd (e.g.
abstractions), Lua, and other languages, we should consider
treating all of these implementation methods as equals.
