Bug fix: Strict inequalities and inequal

Examples:

Here is inequal . Note that the region is drawn as if the inequalities were x+y < 0 and x > 0.

> plots[inequal]({x + y < 1, x > -1}, x=-2 .. 2, y=-1..3, optionsfeasible=(color=cyan), optionsexcluded=(color=blue));

[Maple Plot]

Here is a correct picture as drawn using inequalities .

> inequalities({x + y < 1, x > -1}, x=-2 .. 2, y=-1..3, optionsfeasible=(color=cyan),optionsexcluded=
(color=blue));
