Advisory: beagle-0.3.0 crashes at start

Problem: For beagle-0.3.0, beagled crashes when started. The stacktraces look 
like (once for each backend):

Error: Caught exception while instantiating Files backend
System.Reflection.TargetInvocationException: Exception has been thrown by the 
target of an invocation. ---> Mono.Data.Sqlite.SqliteException: Sqlite error
no such table: textcache_data
  at Mono.Data.Sqlite.Sqlite3.Prepare (System.String strSql, 
Mono.Data.Sqlite.SqliteStatement previous, System.String& strRemain) 
  at Mono.Data.Sqlite.SqliteCommand.BuildNextCommand () [0x00000] --- End of 
inner exception stack trace ---

Fix: Delete ~/.beagle directory. Also, r4251 fixes the problem.

Explanation: The format of all data stored in ~/.beagle changed from 0.2.x to 
0.3.0. It was ensured that all the different kinds of old data were purged or 
upgraded to the new format. Unfortunately, this check was missed for the 
TextCache.db textcache data. As a result, users who were using beagle-0.2.x 
with sqlite3 will see beagled crashing when trying to start the backends.

This will not happen for users running sqlite2 earlier, since their database 
will be automatically deleted. Since almost all of beagle-0.2.x data is 
incompatible with beagle-0.3.0, all of them are anyway deleted when beagled 
is started; except config files, which are modified according to the new 
format. If there are no config files in ~/.beagle/config, deleting ~/.beagle 
will not cause any additional loss of data.
