Expose boolean table cell to python

[Owen Arnold]

At the moment, fetching the value of a cell containing a boolean type will result in a error complaining that the c++ type cannot be converted to a bool.

This issue was identified as part of the testing for #7325.

Currently, running this:

ws = CreateEmptyTableWorkspace()
ws.addColumn('bool', 'a')
ws.addRow([True])
ws.addRow([False])

print ws.cell(0, 0) # Expect True back
print ws.cell(1, 0) # Expect False back

Gives this:

ValueError: Cannot convert Python type to C++: bool at line 3 in

refs #7371. Fix cell setting and fetching and test.

Tester: Run the script in the description. It should fail on an older version of mantid without these changes. Then run the script with these changes applied. Should print True and then False on separate lines.
