Tell wget to retry for connection-refused errors.

* This should help the build process to survive short-lived connection 
  problems (as they happened to buildbot slaves tonight).
Added application/xhtml+xml to StyledEdits supported types.
shortcut_catcher: Small refactor to FindPaths()

Should be functionally identical.

* Removed / after Tracker, thanks Axel.
* BString::FindFirst() returns an index not a status_t so check that
  it finds the path at the start of the string (index 0).
* Put paths.CountStrings() in a count variable.

I wanted to clean this code up because I use it as a reference.
shortcut_catcher: Add Jessica Hamilton to authors

... with permission to recognize her contributions here.
Tracker: small refactor to FindPaths.

No functional change intended.

* Remove trailing / from Tracker, thanks Axel.
* put addOnPaths.CountStrings() in a variable.
App Server: Style fixes to AccelerantHWInterface
App Server: Refactor Accelerant add-on loading

... to use BPathFinder instead of iterating through each of the
(current) add-on directories.

Update copyright header, add myself to authors.

add an ATRACE() of the path once it is found.
listimage: style fixes

Also use puts() in place of printf() in a couple places
where no string interpolation takes place.

Replace the variable name "status" with "result", I just like
it better that way for easier grep-ability.
listimage: A bunch of small fixes.

* Use arch-independent format specifiers.
* Print pointers at a fixed length padded with 0s,
  length is eitther 8 or 16 depending on pointer width.
* Uppercase titles.
* Add an extra space between Data and Seq# columns to
  more clearly show that they represent separate titles.
* Move the Name column last because it is variable length.
  This way, all columns line up vertically and the name can
  overflow past the end, before a long path would push all
  the other columns to the right.
* Make the Name column title is left-aligned, dashes go to
  80 cols.
* Use C89 comments and C89 variable declarations.
