Couple of fixes in the examples
More example fixes
Reduced size of marker images
Pagination of place results, refactors & fixes

- Finally figured out how to get all the results were we after (was sure
there was more than I was getting).  Google Places API pages the
results, so added a "more" button to get .... erm ... more results.
- Places lookup refactor.  We were hitting the API lots when we first
loaded up the places.  This wasn't necessary and we were hitting the
query limit lots too.  Refactored so we lookup places on demand rather
than for every place.
- Changes the control buttons to be actual buttons rather than
hyperlinks (to be honest, they always should have been!)
- Fixed issue with the telephone hyperlink which wasn't marked as being
a telephone number and was therefore clickable
