Details:

The package name tends to be lowercase, but the code in pkg.m and its
subfunctions handles the package name inconsistently. Sometimes it needs to
match exactly, including case, and sometimes the case does not matter.

In my opinion, case should be ignored in all cases, all comparisons with
package names should be case insensitive. This would be consistent with the
'pip' package manager for Python.

Example:


>> pkg install -forge Signal
For information about changes from previous versions of the signal package,
run 'news signal'.
>> pkg install -forge SIGNAL
For information about changes from previous versions of the signal package,
run 'news signal'.
>> pkg install -forge sIgNaL
For information about changes from previous versions of the signal package,
run 'news signal'.
>> pkg load sIgNaL
error: package sIgNaL is not installed
…
>> pkg uninstall sIgNaL
warning: some of the packages you want to uninstall are not installed
…
>> pkg load SIGNAL
error: package SIGNAL is not installed
…
>> pkg unload SIGNAL
error: pkg: package(s): SIGNAL not installed
…
>> pkg uninstall SIGNAL
warning: some of the packages you want to uninstall are not installed
…
>> pkg describe Signal
error: some packages are not installed:  Signal 
…



I think all of these should work equivalently regardless of the case the user
types or the case that the package maintainer chose to put in the DESCRIPTION
file.
