SAK-27774
SAK-25857

Completely walk through the inlining process to look at how tools that
use the suppress-title function (a.k.a. Lessons).  The portal code's
attempt to support these suppress-title tools  was a mess to say the least.
The biggest issue is the "Reset/Home" button across various types of
tools (Velocity, JSF, RSF, Wicket etc).  This cleans up
the flow through the Handlers and Skinnable Charon Portal.

- Remove support for the never used SAKAI_PORTAL_BREADCRUMBS
- Clean up the processing of tool-reset so we only do it once
- Remove the neo strings from session when no longer needed
after inlining (SAK-25857)
- Clean up indentation on SAK-28086 / r315621
- Remove redundant, unused and now incorrect code that supported the
original portal.experimental.iframesuppress feature in Sakai 2.5 (r35170)
from ieb in IFrameToolRenderService.java
- Add extensive debugging to diagnose issues with inlining. Convert print
statements from SAK-28086 into debug statements.  These can be viewed with
sakai.properties statements like these:

log.config.5 = DEBUG.org.sakaiproject.portal.charon.SkinnableCharonPortal
log.config.6 = DEBUG.org.sakaiproject.portal.charon.handlers.PDAHandler
log.config.7 = DEBUG.org.sakaiproject.portal.charon.handlers.SiteHandler
log.config.8 = DEBUG.org.sakaiproject.portal.charon.handlers.ToolHandler
log.config.9 = DEBUG.org.sakaiproject.portal.charon.handlers.DirectToolHandler
