[EGIT PATCH v2 00/12] Support customizable label decorations

["Tor Arne Vestbø" <torarnv@gmail.com>]

This series adds support for customizable label decorations, which
is usefull for hiding selected decorations, or tweaking the format
of the decoration text.

Changes in v2:

  - Fixed layout issues in preference dialog
  - Icons replaced to match established conventions
  - 'Assume unchanged' icon is back
  - Added tooltips in the preference dialog
  - 'Added and dirty' is now decorated appropriately
  - Refactored container decorations. Now shares code path with
    files for more accurate results, and to allow inheritance

Decorations are edited using the new Team->Git->Label Decorations
preference page, which is based off similar functionality from the
existing CVS and SVN team providers.

Icons can be enabled and disabled individually, and text can be
customized by reordering and editing the set of mapped variables.
Boolean variables like 'dirty' and 'staged' can be customized by
postfixing the variable name with a colon and a selected string
that should be insert if the variable evaluates to true.

The two general options control traversal of child and parent
elements during decoration. The first, 'Also re-decorate...',
controls whether or not ancestor elements of the current decorated
elment will also be scheduled for re-recoration. The second, 
'Maximum number of levels...', controls how deep the container
decoration algorithm will recurse when trying to determine the
state (dirty, staged, etc.) of a container.

Tweaking these options will improve performance for large trees.

The code should work fairly well for most usecases, but I may have
missed cases where the decorations will fail misserably. If so, 
please let me know. 

Known issues are:

  - If a project has a repository more than one level above the
    project directory decorations will fail.

  - When a Java resource is dirty, each package in the package
    hierarcy will appear dirty, also when the layout is set
    to 'flat', which can be confusing.

These are on my list for features to add on top of these series,
but I consider them non-blocking. This also goes for online help,
which will be added when things stabilize some more.

I've also sprinkled the code with TODOs where I found possible 
future improvments. One such improvment is performance, where for
example refactoring to use one shared status cache should help.
