Try to fix unicode problems in reading "source" files.
Keep track of thermo matches and show in thermomatches.html view

As well as putting in the tentative matches list (although I am not sure 
about this really, as sometimes we match thermo of several conflicting
species) we now (also) store thermochemistry matches in a separate list
of thermo matches. There is a new web view to see this list and confirm them.

Currently there is no web link to clear an incorrect match from this list.

Also, when making matches, we now continue beyond the first matching hit, so
we can tell if it matches the same species from more than one library.
Look in sister directories for other (incomplete) thermo libraries.

In the end we should put all these in the database, but for now we tend
to have .thermo.py files lying around neighbouring directories of the model
we are importing, so we may as well use them.
Fix a bug in confirming thermo matches, but introduce another.

Don't have time to fix this one now, but it's closer than it was before,
and more obviously wrong.
Fix the clearing and confirming of thermomatches.

Had to get the RMG species from the RMG species's name: str(rmgSpecies)
Best way is to check everything that's a thermomatch.
Added a 'clear thermo match' link/view.
Good/bad thermo matches (based on names) coloured in green/red.
Count of thermomatches shown on index page
Fix for Python 2.6 on Pharos
Don't put thermo matches in tentative match list.

Now that we have a dedicated thermo match list
Parse more malformed chemkin thermo files.

Some people put random "0    " blocks in where there should 
be element specifications.
Keep waiting for web front end.

Before it would only bother waiting if it thought there was a tentative match
to click, but now there are other ways to help it out (such as entering a thing)
and we often run with an unattended terminal (eg on a cluster) so this
makes more sense.
Draw pictures of thermo matches
Added a new function for enlarging the model. Currently
has the same functionality as the previous enlarge.
Some new species in n-Heptane.
Rewrite the enlarge code to now only react species
with other species they react with in the chemkin 
file.
