NarraFirma 0.9.3

This version fixes GitHub issue #4. It makes some cosmetic changes, most notably to improve the labels for sliders for use with narrow mobile screens to be clear about which label is low and which is high. It also adds a readme.txt file needed to include NarraFirma in the official WordPress plugin archive.

To use the WordPress version, you upload the WordPress plugin zip file (narrafirma-wordpress-plugin-v0.9.3.zip) directly into WordPress from the plugins section of a running WordPress installation. You can download that plugin zip file from the following link for this release. Be aware that zip file is a different file than the entire source code in narrafirma.zip. After you install the plugin, you will need to create a project from the NarraFirma plugin panel and specify what users have read or write permissions for the project.
