Tutorial .rst needs fixing

[Garth Wells]

The tutorial .rst files were generated automatically from the .tex file, which is not perfect. Tutorial files needs to be checked and fixed.

in the web tutorial (as well as in the book draft available online) there is a piece of code not compatible with current PPA FEniCS version; I refer to the first code appearing in http://fenicsproject.org/doc/tutorial/fundamentals.html :

# Compute solution
problem = VariationalProblem(a, L, bc)
u = problem.solve()

Running the code as is will result in the output error:

*** Error: Unable to create variational problem.
*** Reason: The VariationalProblem class has been removed. Please visit http://fenicsproject.org/releases/1.0-beta/ to see which changes you need to make to your program..
*** Where: This error was encountered inside variationalproblem.py.

This should be changed to (based on the link in the error output):

# Compute solution
u = Function(V)
problem = LinearVariationalProblem(a, L, u, bc)
solver = LinearVariationalSolver(problem)
solver.solve()

Thanks for the report. We are aware of this and will fix as soon as
possible.
