[Owncloud] 4.5 RC1

[Duarte Velez Grilo]

After upgrading:

{"app":"core","message":"Failed to update database structure (MDB2
Error: unknown error, _doQuery: [Error message: Could not execute
statement]\n[Last executed query: CREATE INDEX
`appconfig_appid_key_index` ON `oc_appconfig` (`appid`,
`configkey`)]\n[Native code: 1071]\n[Native message: Specified key was
too long; max key length is 1000
bytes]\n)","level":4,"time":1348744168}

And I can't even login, because the page only shows: "Error while
upgrading the database". The previous beta didn't have this problem.

Cheers,
Duarte
