added __repr__ method to database which outputs numbers of objects
Merge branch 'hotfix/1.0.1' into develop

Conflicts:
	oecpy/__init__.py
fixed some typos in docstrings
fixed requirement for database path to end in '/'
changed transit time to units of JD not day. fixed ParseError being raised over LoadDatabaseError seemingly randomly when there is no root (i.e. system) tag
no need to import quantities anymore, astroquantities imports all pq units to its namespace
fixes for previous commit (python 3.4 has no exception.message and 2.6 has no ET.ParseError)
- python 3.4 has no exception.message so the exception is just printed instead (which does the same thing))
- python 2.6 raises xml.parsers.expat.ExpatError instead of ParseError
updated setup.py email and added python3.4 to support versions.
added dictionaries fro stars, binaries and systems in database
Renamed flags.Flag to .Flags, removed str method from Flags so __repr__ and __str__ reports Flag(flags). Added __iter__ to Flags for if x in flags
changed 'Fake Planet' tag to 'Fake', example planets all have this flag raised
Added pie charts to binned plots .plotPieChart()
Added function to automatically load the catalogue from the web with 'load_db_from_url()' using the gripped version at "https://github.com/OpenExoplanetCatalogue/oec_gzip/raw/master/systems.xml.gz"
updated version number
Merge branch 'release/1.1'
