changed default location of nwcloud.properties

request to move  nwcloud.properties from ./ (current directory) to ${user.home}/.nwcloud

with nwcloud.properties in the project directory, no way to use the maven-release-plugin it not by submitting the nwcloud.properties (incl. password) to the scm.

(it must be precised that I have hooked the nwcloud:deploy goal to the maven:deploy lifecycle, as shown around line 50 of https://github.com/cthiebaud/abendrot/blob/1f668c0ea76e7c94a846d8abe3f8f6952945ed37/pom.xml)

also, as mentionned in my blog : http://cthiebaud.github.com/abendrot/, it is unsafe to have a file containing potentially sensitive password in a source directory. ~/.nwcloud location seems more appropriate.

thanks
