After much thought and deliberation... a change in EPANET repo

policy regarding Makefiles and their output targets.  
Used to create library and executable file names that included
the compiler (e.g., *_gcc_*) and the SVN rev (*_309_*).  This
was to allow development along the trunk while keeping clean track
of the SVN versions that objects were made from.  

Maybe a good idea in part, but no longer.  It collapsed under its
own complexity.  The need to keep track of all the specific
file names became more burdensome that the need to keep track
of which source actually built an object.

As of now, Makefiles produce unadorned file names:

Linux:
lib<name>.so
<name>
Cygwin:
cyg<name>.dll
cyg<name>.exe
libcyg<name>.dll.a
MSVC:
<name>.dll
<name>.exe
<name>.lib
MinGW:
Same as MSVC
Darwin:
Don't know about this, but I think they already were produced
with just dy extensions

Under this scheme MinGW looks just like MSVC, but I guess that's 
the whole point...
