Description

Starting MantidPlot on a RHEL5 machine causes this error: 

Traceback (most recent call last):
  File "<string>", line 17, in ?
  File "/SNSlocal/tr9/Mantid/Code/mybuild/bin/MantidFramework.py", line 821, in initialise
    self._importSimpleAPIToMain()     
  File "/SNSlocal/tr9/Mantid/Code/mybuild/bin/MantidFramework.py", line 854, in _importSimpleAPIToMain
    mod = reload(sys.modules[simpleapi])
  File "/home/tr9/.mantid/mantidsimple.py", line 16313
    print 'mtdHelp() - ' + cmd + ' not found in help list'
SystemError: com_backpatch: offset too large
Error running init file "/SNSlocal/tr9/Mantid/Code/mybuild/bin/mantidplotrc.py"

to be raised resulting in the failure to initialize Python.

It looks to be a problem that the mtdHelp() if/elif chain of statements has become too long.

(In [8812]) Create the python mtdHelp function in a much smarter way. Aboids a (very long) chain of if/elif statements that the python interpreter on RHEL5 didn't like. This way it doesn't matter how many algorithms we have. Re #2254
