- When compiling additional modules or user code, we need more control
  for the installation locations beyond the usual FOAM_USER_LIBBIN,
  FOAM_SITE_LIBBIN, FOAM_LIBBIN, and wish to have these values be
  modifiable without editing files.

- provide wmake rules for handling standard defaults:
    * GENERAL_RULES/module-path-user
    * GENERAL_RULES/module-path-group
    * GENERAL_RULES/module-path-project
  which are incorporated as follows:

  Make/options:
      include $(GENERAL_RULES)/module-path-user

  Make/files:
      LIB = $(FOAM_MODULE_LIBBIN)/libMyLibrary

  By default these would compile into FOAM_USER_{APPBIN,LIBBIN} but
  could be adjusted at compilation time. For example,

```
wmake -module-prefix=/path/my-install-location
```
Or
```
./Allwmake -module-prefix=/path/my-install-location
./Allwmake -prefix=/path/my-install-location
```
Or
```
FOAM_MODULE_PREFIX=/path/my-install-location ./Allwmake
```
