Page manager handlers needs to have sustainable machine names

Had a look at this. There was one handler in ns_search that had the default handler name, patch fixes that. Other than that I think they look ok. See grep below for state after patch applied to ns_core.

grep -R '$handler->name =' .
./features/ns_ch_blog/ns_ch_blog.pages_default.inc:  $handler->name = 'ns_ch_blog_blog';
./features/ns_ch_blog/ns_ch_blog.pages_default.inc:  $handler->name = 'ns_ch_blog_blog_post';
./features/ns_ch_blog/ns_ch_blog.pages_default.inc:  $handler->name = 'ns_ch_blog_site_template';
./features/ns_ch_blog/ns_ch_blog.pages_default.inc:  $handler->name = 'page_ns_ch_blog_blog_panel_context';
./features/ns_ch_web/ns_ch_web.pages_default.inc:  $handler->name = 'ns_ch_web_article';
./features/ns_ch_web/ns_ch_web.pages_default.inc:  $handler->name = 'ns_ch_web_article_draft';
./features/ns_ch_web/ns_ch_web.pages_default.inc:  $handler->name = 'ns_ch_web_article_revision';
./features/ns_ch_web/ns_ch_web.pages_default.inc:  $handler->name = 'ns_ch_web_default';
./features/ns_ch_web/ns_ch_web.pages_default.inc:  $handler->name = 'ns_ch_web_site_template';
./features/ns_ch_web/ns_ch_web.pages_default.inc:  $handler->name = 'ns_ch_web_topic';
./features/ns_ch_web/ns_ch_web.pages_default.inc:  $handler->name = 'page_ns_ch_web_promos_panel_context';
./features/ns_ch_web/ns_ch_web.pages_default.inc:  $handler->name = 'page_ns_ch_web_topic_editor_panel_context';
./features/ns_search/ns_search.pages_default.inc:  $handler->name = 'ns_search_node';
./features/ns_ch_rss/ns_ch_rss.pages_default.inc:  $handler->name = 'page_ns_ch_rss_topic_editor_panel_context';
./features/ns_ch_rss/ns_ch_rss.pages_default.inc:  $handler->name = 'page_ns_ch_rss_topic_list_panel_context';

Oh maybe these are also lame names?

page_ns_ch_blog_blog_panel_context
page_ns_ch_web_promos_panel_context
page_ns_ch_web_topic_editor_panel_context
page_ns_ch_rss_topic_editor_panel_context
page_ns_ch_rss_topic_list_panel_context
