Add way to get a table's name

[msiemens]

See https://forum.m-siemens.de/d/23-table-name-from-the-table-object

My main concern is how to add this in a backwards-compatible way, as I'm not totally sure what guarantees we specify in the docs about what arguments the table class should take.

@msiemens, wouldn't you just add a readonly attr to store/read the table name?

@msiemens, I made 3 changes in the database.py to store and access the table name. I didn't want to do a pull request etc... I am not good enough for that, i am still a beginner. Also, its probably not so Pythonic what i have done. Anyway, i just wanted to give it a go. But it does seem like this would not change the interface. Not sure about custom tables etc...
In the def table method, I updated the options kwargs with the name of the table, which is present. Then in the Table class init, i added a new kwarg param as well as a attr and a property to store and access the attr. In my simple cases, it appears to work.

def table(self, name=DEFAULT_TABLE, **options):
		"""
		Get access to a specific table.
		
		Creates a new table, if it hasn't been created before, otherwise it
		returns the cached :class:`~tinydb.Table` object.
		
		:param name: The name of the table.
		:type name: str
		:param cache_size: How many query results to cache.
		"""
		
		if name in self._table_cache:
			return self._table_cache[name]
			
		options.update({'table_name':name})	# <--- added this
		table = self.table_class(StorageProxy(self._storage, name), **options)
		
		self._table_cache[name] = table
		
		# table._read will create an empty table in the storage, if necessary
		table._read()
		
		return table

class Table(object):
	"""
	Represents a single TinyDB Table.
	"""
	
	def __init__(self, storage, cache_size=10, table_name=''): # added new kwarg
		"""
		Get access to a table.
		
		:param storage: Access to the storage
		:type storage: StorageProxyus
		:param cache_size: Maximum size of query cache.
		"""
		self.__table_name = table_name # <-- private attr added
		self._storage = storage
		self._query_cache = LRUCache(capacity=cache_size)
		
		data = self._read()
		if data:
			self._last_id = max(i for i in data)
		else:
			self._last_id = 0
		
	# property added
	@property
	def name(self):
		return self.__table_name
	
	# class continues...
	
	```

Hey, sorry for the long delay, I've been pretty busy lately. All in all, your changes look pretty good, I've implemented them in 58e2ab7, I'll release a version of TinyDB that includes this feature later today :)

Now released in v3.5.0 🎉

Perfect, thanks for the update. I am just having some fun at the moment trying to use TDB as an old style macintosh resource manager. I started out doing this as in the old old days, I used the mac resource manager to hold string translations for the UI languages. As I am using Python on iOS i dont have direct access to plists etc... I am sure you are too young to remember the resource manager, but in my option it was fantastic. TDB seems like a perfect foundation to build a puesdo resource manager around.
Thanks Again
