[Cpptool-develop] tests added

[Sven R. <rei...@ma...>]

I added a few more tests for rename temp. It looks that so far it does a 
simple text replacement (after extracting the correct variable name from 
the declaration). I could make some more of these tests run, but only with 
some crude hacks. What do you think of one further parsing step that 
splits an expression into tokens (applied only when it contains the string 
we're interested in)? Tokens so far are just legal identifier names, "::", 
"->" and "."; the rest can be kept as source code.
