ECB 1.30 released

ECB 1.30 is now released. Improvements since 1.20:

- If not all ECB-tree-windows of current layout are visible at redraw-time
('ecb-redraw-layout') then the redraw synchronizes the contents of the
tree-windows with the source displayed in current edit-window (Klaus).

- Added a section "Tips and Tricks" to the ECB online-help. (Klaus)

- Added a new layout Nr. 10 for very small screen resolutions where all
squarecentimeters are needed for the editing itself. This layout only
displays a method-window and a edit-window. (Klaus).

- The messages displayed after moving the mouse over a node in a tree-buffer
do not longer wasting the log, means they will not be logged (Klaus).

- ECB now also works with semantic >= 1.4 (Klaus).

- Now the ecb-compile-window-height is also preserved after displaying
temp-buffers (e.g. help-buffers after C-h f) - if you want this. See the
documentation of the option 'ecb-compile-window-temporally-enlarge'. (Klaus)

- Added menu items for modification of the source paths in the directories
buffer. (Jesper)

- Added buttons to directories buffer. (Jesper)

- Mouse over files, methods etc. now work even if follow-mouse isn't
activated (Jesper). ECB adds a more intelligent mouse tracking mechanism, so
not only the mouse-over-node stuff of ECB works now very well and savely but
also follow-mouse itself works better and saver as without activated ECB.
(Klaus)

- Popup menus now work in XEmacs. (Jesper)

- You can now specify paths with env-vars like $HOME in the option
`ecb-source-path'. (Klaus)

- The user must now confirm if he tries to delete the ECB frame. If he wants
to proceed then ECB will be first deactivated before deleting the frame.
This works for all ways to delete a frame (shortcut, window-manager-button,
...). (Klaus)

- ECB now optionally create its own frame when activated. See the new option
'ecb-new-ecb-frame'. (Klaus)

- Intelligent recentering of tree-buffers now completely implemented without
the function 'recenter'. This means no flickering and flashing the whole
frame anymore after each 'recenter'. Now the ECB display is stable like a
rock :-) (Klaus)

- Mouse over directories now shows directory path. (Jesper)

- Methods and variables with point are now highlighted. (Jesper)

- ECB windows are now updated when saving new files and deleting files. (Jesper)

- incremental-search in every tree-buffer for easier and faster selecting
nodes with the keyboard (see new option `ecb-tree-incremental-search' and
new function 'tree-buffer-incremental-node-search') for more details.
(Klaus)

- ecb-redraw-layout now restores both edit window buffers and the edit window
start. (Jesper)

- Spelling corrections. Thanks to Colin Marquardt
<colin.marquardt@usa.alcatel.com> for spotting them.

- Mode line prefixes can now be set individually for each ECB-buffer. There is
a default-prefix for each buffer but the user can also define a custom
prefix or no prefix at all. (Jesper/Klaus)

- Fixed small bug in directory tree that caused directories to be sorted by
extension. (Jesper)
