Ignore rules have inconsistent case-sensitivity

In Quassel Desktop (0.13.0), dynamic ignores (of messages and senders) are case-insensitive. In QuasselDroid (1.0.5), they are case-sensitive. For instance, if you have an ignore rule for /justjanne.*/ and receive a message from JustJanne, Desktop will ignore the message, while QuasselDroid will happily display it and generate notifications/sounds as normal. This also applies to wildcard and message rules.

The expected behaviour is case-insensitivity, as Desktop does (and which is consistent with how casing is treated for decidng what buffer a message goes into).
