Ineffective setting of m_nVersion in AddFieldNative function

[mloskot]

In file mitab_miffile.cpp:1783, there is a suspicious case that looks like:

case TABFDateTime:
   ...
   break;
   m_nVersion = MAX(m_nVersion, 900);
case TABFLogical:
...

The m_nVersion assignment is a dead code, perhaps unintentional.

This was already fixed in the CVS master upstream (in mitab_miffile.cpp CVS r1.51 2009-07-27). Seems that we need to update the local copy from the master.

I committed the fix for this in SVN trunk r20158
