These 4 files contain dde-links to calc.exe and are encrypted with
excel's standard password.

These are encrypted with the standard password hard-coded into excel to
implement a form of write protection

oleobj: detect external links

Checks output on all data in tests/test-data dir

Samples were created by me using Office 2010 on a Windows 7 machine,
password is "encrypted", contents is trivial (no links, macros, ...)

Encryption should be the CryptoAPI RC4 Encryption (see [MS-OFFCRYPTO])

Unittests worked on Travis and from IDEs like PyCharm, but from
command line I had to change log helper test root dir to one level up
and unset PYTHONPATH

The OutputCapture was a slightly hacky way to get output from scripts without
using subprocess. However, keeping it working started requiring reloads since
module's logs are global variables which were re-initialized which caused
trouble). That required reload of all submodules, so more hacks are needed
to keep the initial hack "alive". Therefore I am glad it is not needed any more
and can be removed.

Some msodde tests call the main() function from the module
which tries to enable logging, causing lots of problems
when running multiple tests due to the singleton dependency
of the logging modules.

Since what they want to test is whether msodde is finding
links, we can use the process_file() function directly
instead and check its output.

oleid: detect OpenXML encryption

Fix some PEP8-related linter complaints.

Word does not accept files which magic is not fully
lowercase.

The pre-read test found a bug in oleobj for zipped-xml files. Will fix with
next commit.
