A wfDebugLog() was attempting to concatenate a string with a Blob object
which does not support conversion to a string. Since that was used to
show some hash, display the current string hash instead.
Furthermore the input-hash, which can be calculated from the TeX input
string was displayed, which is not very helpful. The variable hash is
calculated by texvc and can be used to search for the rendered image in
the filesystem.

adds two new phpUnitTests for the abstract MathRender class
and another one that test the basic database access.
Therefore the read and write methods have been made changed
from protected to public.

Output hash calcuation sometimes fails because of Texvc failure for
example, and $this->hash remains ''. At this time inserting null as
outputhash into database is improper, because that column is NOT NULL.
With this patch an empty string '' is inserted instead, and the if-check
is modified to avoid cases where ->hash exists but evaluates as null
(for example when it's '0000000000...' though it's extremely rare).

The call to getRenderer is supposed to be a static method in the same class,
not a global function.

The Math.body file which contains the MathRender class was split in the following way:
- Math.base contains the base class with the database related stuff and provides an abstract interface
- Math.source and Math.MathJax handle the plain tex string output. There are two classes since they
will differntiate in the future I think.
- Math.texvc contains the "old" implementation of png generation with all the file handling related stuff
- Other implementation of math renderer can be added in the same style.
- Cleanup to better follow coding conventions.
- Changed LockManager to 'fsLockManager'
The first attempt restructure the class layout and introduce LaTeXML at the same
time was dropped. Instead this was split up into two phases.
This commit only deals about the restructuring of the math module design.
