File encoding and line ending changes. [0]

The files in edu.wisc.ssec.mcidasv.data.dateChooser were CRLF and
encoding other than UTF-8. This commit won’t be “diff” friendly, so I
preemptively apologize for that…but FWIW there are no “logic” changes.
Nicer implementation of level-slicing functionality.

NOTE: "level" parameter should now be a string, e.g. "1000 hPa".

- unit conversion handled automatically
- Subset is done before data actually gets read, so things happen
  much faster when loading a single level
- Data probe issue should be fixed

Better time slicing implementation also.  This one shouldn't have any
effect at user-level, other than faster load times if working with file
containing time sequence

[1589]
First stab at handling time sequences made with loadFile.

Still some work to do but for now it works for basic test case.

For example script / test data, see updated wiki:
