Fix nclua runtime files location in both source code and deployed folder in windows

[alanlivio]

See errors bellow.
Today, we workaround creating in deployed version by creating C:\Program Files (x86)\Ginga\ginga with content of C:\Program Files (x86)\Ginga. Then create C:\Program Files (x86)\Ginga\share and C:\Program Files (x86)\Ginga\lib folders with nclua required files.

error in source code folder:

@gflima, do you suggest something?

Try making the executable (ginga or ginga-gui) set both LUA_PATH and LUA_CPATH to the directory of the .lua's and .dll's when it's on Windows. This can be done using setenv().
