Add support for 'A', 'E', 'I' in LINEELE URLs.

'I' is the default (per VisAD's AddeURLConnection docs).

Some clean up. [1825]

Always show sampling label. [1825]
Bring over NPE fix from IDV. [0]
Ignore %RESOLUTION% macro when not in use.

Even more clean copies. [1826]
Add dummy active view button. [1826]
Show rubber band box and default to select region

This one provided a good long night of head bashing. :(

Slightly better icon, use "A" key rather than "M".

[1826]
Remove superfluous code. [1826]
Disable preview "undo" button when applicable.

There’s a strange issue with the button not *appearing* to be disabled
after initialization…even though the value of zoomBack.isEnabled() is
false!

*cue the x-files theme*

Associate active ViewManager with NavigatedPanel.

Getting close to having the “active view” feature working…

[1826]
Use VMManager to get active ViewManager. [1826]

…and now we have a proof of concept implementation of the “active view”
feature request!
Add Vim .swp files to .gitignore

[0]
Clean up and javadoc. [1826]
Use VMManager to grab most recent ViewManager.

This means that clicking the “use active view” button will now always
use the region of the currently active (navigated) ViewManager (rather
than the one that was active when the panel was created).

Fix for advanced tab defaulting to disabled.

[1825]
Fix problem with data selection disappearing.

If you were to preview an image, select some other option besides
“Select A Region”, and then reselect “Select A Region”, the region
selection would not be restored.

[1825]
Specify band for preview image. [1825]

This seems to fix the problem Bob discovered with that “500 very small
AREA files” test.
