Patch for two issues

[Kocik, W. <wk...@ve...>]

Hi -

In the course of working with DNSJava I¹ve encountered two issues which are
addressed by the patch below my signature:

1. LOCRecord.java ­ a LOC record with a negative altitude would cause a
NumberFormatException from parseFixedPoint() when reading a zone file,
because it used a regular expression that did not account for the potential
presence of a Œ-¹ character at the beginning of the number
2. ExtendedResolver.java ­ sendAsync() was not using its multiple resolvers
to send a message, only the first one on the array.

Hopefully my fixes are acceptable, but if they aren¹t I¹ll gladly help find
more appropriate solutions.
