add OSGEO4W to PATH

[timmie]

Please automatically add

c:\OSGeo4W\bin\

to the Windows PATH.

Timmie,

We deliberately do *not* do these for two reasons.

1) adding this directory to the path is not sufficient to setup some required aspects of the environment.

2) it would be difficult to control the conflicts this might cause with others software with similar dll names, and to have multiple versions of things living safely on the system.

So, for the time being if you want an OSGeo4W enabled command shell you need to click on the OSGeo4W shell, or run the osgeo4w initialization script from another shell. Also the desktop icons run scripts to setup their environments during startup.
