minor fix to avoid error when gwc data is missing
Merge branch 'master' of https://github.com/boundlessgeo/suite-qgis-plugin
fixed wrong code when showing invalid data warning in pg config dialog
fixed #113 (PostGIS Credentials window has mis-aligned text boxes)
use tempdir for writing nose output, refs #119
tests - catalog params via env variables,refs #120
fix dock title, closes #122
fix for #121, get layer title from resource

this was most likely related to removing gsconfig - i think
there was a modification i missed moving over
