[RMMV-MZ] Horizontal Scrolling

v1.00 - Initial Release
v1.06 - Bugfix
v1.11 - Added parameter feature, made a MV version & also a bugfix
v1.21 - Added new parameter to "force" a window to become horizontal

This plugin adds left/right arrows for windows and adds scrolling horizontally to scrollable horizontal windows

A horizontal window is a any window with only 1 row

Able to change number of visible columns of any window via parameters

or...

overwrite the following function via it's own added plugin file

 ~WINDOW_NAME_GOES_HERE~.prototype.numVisibleCols = function() {
     return this.maxCols();
 };

 Example:

 Window_ShopCommand.prototype.numVisibleCols = function() {
     return 2;
 };

Doing that would then make the Shop Command Window only show 2 rows but be then be scrollable for it's full command list
