Account Tracker / Hill Lists / Meter Readings

Updated the underlying data to use version 14 of the Database of British and Irish Hills. This includes some minor hill changes, plus the Binnions list now includes hills with a drop of only 100m (was 150m).

Added a description of the summit feature for over half the hills in the app, very useful in the mist!

Added external links to hill-bagging.co.uk (for all hills).

Added support for using the Apps folder on Dropbox. To change, simply unlink and re-authorise the app to Dropbox. Note that you will need to copy any files yourself, either from the app or by using a computer.

Worked around an issue where access to MWIS forced the app to quit to load Safari (iPad only).

Note that the minimum iOS version is now 5.1.1.
