Patch Launcher To Allow More Icons Per Row

THIS IS 1.1.0 SAFE, DO NOT TRY IT WITH ANY OTHER WEBOS VERSION

Introduction

This patch allows you to have a 20 icon, 5x4 launcher page. It decreases icon size and text size, changes the apps per row, and moves the text closer to the icon. It also modifies where the page indicators and margins are a little.

End Result

Here's what your launcher looks like after the patch is applied:

Patch Process

If you are not familiar with the Webos-Internals patching process, you'll need to visit the Applying Patches section of the wiki to know how to use the patch. After you have set up everything and are ready to download the patch, it is in the modifications repo under "luna/more_icons_per_row.patch" ===address forthcoming===

This patch also includes the patch to allow a user to add and remove additional launcher pages. You might have to remove that patch before applying this one.
