[Somelib] Directory loading now implemented

[John P. <jo...@ma...>]

I moved the framework for loading directories into XPPath and Path
objects.  I need to seperate out the XPPath interface from
implementaion.  You can still use regular strings to load specific libs
for backwards compatability.  Path takes a name of a directory or a file
name.  I will implement wildcard searches later.  An example on how to
use the Path object is in complexmenu.  It is only implemented under
linux right now.  Path.cpp must be created for each platform (though
I suspect that the HPUX and linux versions are similar).  I tried to no
avail to make it as easy as Path p = "plugins"; to use.  I overloaded
the assignment operator and gave the base XPPath class XPPath::XPPath(
string ) constructors (and const char *) but it still didn't want to
compile.  Oh well.

We can add another platform to the lists of hosts as I have gotten it to
compile on FreeBSD.  Turns out that the libdl functionality is located
in the stdc lib on FreeBSD (and I suspect otherBSD's)  I will get around
to updating the config so that it checks for libdl and then for the dl
functions in libc.  I will also change the linux target to unix_so, so
I don't piss off the BSD guys, who I find charming but often annoying
(Just kidding) .   How about that - SOMELib on Apple OS X's Darwin :-)
I wonder if they use .so's?  Hehe.

Sun Solaris is next on my list.
