adding the function RunTests to each python unittest allows that the
test is executed either with the default TestRunner or an XMLTestRunner
for producing an XML output file. With no command line argument, the
default Runner is used (same behaviour as previously), with 'xml' as
the first argument, the XMLTestRunner is used.

1. We now read traditional CSV files. Since the files do not explicitly
   specify the column format, we have to guess the format of each column
   after importing.
2. For efficient serialization, table data can be pickled/unpickled
   directly.

1. Option to move libexec to lib/openstructure/libexec
2. Gosty moved to libexec

  - fixed continuous residue numbering (BZDNG-286)
  - fixed bug with empty lines
  - fixed bug with reading residue name in std format
  - write b_factor in EXT format
  - segment name is now cname instead of 'MOL'
  - fixed alignment of residue name in std format
  - add documentation
  - add unit tests
  - possibility to request EXT format

This fixes BZDNG-171

This reverts commit bd6ff2d2.

Changed the behaviour of the ost command line executable.
Exported the GetVerbosityLevel function (formerly GetLogLevel)

added QueryFlags handling to mol::QueryViewWrapper
fixed empty pov output (caused by multiple renderer problem in gfx::Entity impl)
removed GLEW_VERSION_2_0 tokens
various tiny gfx tweaks
added stereo toggling key to gui ('=')
added residue reordering to mol::EntityEditor

moved unit test executables from src dir to tests/, new flag for cmake (wheter to compile unit tests by default), added tests/ to .gitignore

Residues with names shorter than 3 letters are left-padded,
we throw an error if we encounter chain, residue and atom
names that are too long (longer than 1, 3 and 4 characters
respectively) and we try to put the atom name into the
correct column.

Oh, and we insert TER records at the correct positions.

All in all the code is much cleaner and faster as it does
not longer rely on boost.format (yes, io performance is
sometimes critical).
