Use data structures where order remains constant over time [1471]
Removed commented-out "addLayer" method. [1303]

This became "createLayer" instead.
Javadocs. [1499]
Fixed some incorrect javadoc links. [1499]
Fixed startup manager javadoc warnings. [0]

I should probably qualify that by saying the "warnings" refers to the
warnings generated by "ant javadoc".
too eager to deprecate [0]

plus it doesn't make much sense to deprecate a private method. sorry. :(
implemented _Display.getMapLayer() [1303]

Also the implementation is no longer *quite* as dumb.
Fix createLayer error message and use getMapLayer.

D'oh. [1303]

Specialized list class for listADDEImage results.

The intent is to use __str__ to provide output similar to McIDAS-X
IMGLIST, but still behave like an ordinary Python list.

[1303]
Set listADDEImage position default to '0'. [1303]
Old implementation of setCenter method.

Work-in-progress setCenter has been renamed to testCenter.

[1303]
Set logging level before starting the JVM.

The global McIDAS-V logging level can now be set at runtime by setting
the "loglevel" Java system property to one of TRACE, DEBUG, INFO, WARN,
ERROR or OFF. This change allows the startup scripts to set the logging
level to whatever the user last selected.

Default logging level is still INFO.

[1499]
Default position should be an integer value. [1303]

For the sake of consistency (with getADDEImage).
