Check to make sure lastFocus is not NULL before using it.

This prevents an app_server crash on startup for me most likely
introduced in hrev45252. (Just a few commits ago)
Remove remaining /trunk/ before file references.
Move documentation from NodeInfo into the API docs.

* Delete the docs from NodeInfo.cpp and NodeInfo.h
* I snuck a couple of style fixes into NodeInfo.cpp
* I had to make a small modification to MimeType.dox to prevent it
  from overriding the docs of one of the methods in NodeInfo.dox.
Copy-pasta error: storage not app
Moved NodeMonitor docs to Haiku Book.
Some updates to NodeInfo docs
Whoops, NodeInfo.h not Node.h
NodeMonitor doc updates
Move documentation from Path.cpp to Path.dox

And clean it up a bit. Kept brief description in source.
* Also added Axel to authors in Path.dox and Path.cpp because his name
  appears in git blame as working on the docs and code for the file.
  I hope he doesn't mind.
Update translations from Pootle
AppServer: Organize "HWInterface" classes

* Organize interface classes into directories
* Long term this will assist in the multi-head
  interface / accelerant changes.
* local draws to the local hw accelerant
* remote draws to a remote connection (???)
* html5 draws to... an html5 canvas?

Revert "Renamed Tracker option "Don't move files to Trash" (#9352)"

This reverts commit 45f77dcd7029914ccd99178dfb333eb68c7af9e5.
Removed Trash options from Tracker prefs.

As discussed [1][2], using a Trash is in the interest of the
vast majority of users. The setting is still present in the
Tracker settings file. SHIFT+DELETE will still bypass the
Trash.
