GUI with  wxWidgets not using std streams

Link errors with Visual Studio which may have been moving to VC10 or
wxWidgets 2.9.2. Fixed by compiling wxWidgets with wxUSE_STD_IOSTREAM=0,
and replacing wxStreamToTextRedirector() in OBGUI.cpp.
Ignore .pyc, .pyo, etc. from python testing.
Change output flag to avoid stomping on 'm' option.

Avoids error messages from OBConversion about the override
of the 'm' output flag.
Clear the ifs stream flags in the outformat reader.

Otherwise the real format reader fails to read the stream in
rare instances.
Fix tautology reported by clang C++.

If statement with (strlen(line) >= 0) is always true.
Revised to > 0, which was the intended meaning.
Patch from Magnus Lundborg reported to mailing list.

pH model on amidine using -p 7.4 would leave the result uncharged.
Fix potential NULL deference errors indicated by Clang.

Added some "defensive" statements to check for NULLs before
dereferencing. Fixes issues flagged by Clang static analyzer.
