Add cadence logo.
Add a box shadow in some elements in dash.
Add sessionName to config.js
Small optimization to dash.css
Update libraries in Makefile.
Fix Carbon's inputField text color.
Fixed textarea color in all alt styles.
Add /alias command (fixes #35).

This command can be used to define a custom
macro that is stored in the local settings.

Example:

    /alias bye /say Goodbye!; /quit
Link to github repository.
Doubled size of URLs
Add a configure script (part of #8).

Instead of keeping the configuration in the git tree,
use a real config.sample.js template and a configure
script that prompts for variables.

make will put these variables (and the version) into a newly
created config.js file.
Rename muc_service to mucService.
automatically run configure if .config.status is missing.
Allow /save in all modes.
Don't rely on `replace` in make.

replace is actually not a common Unix utility,
but a part of MySQL server. Instead, use sed.
Make configure use arguments instead of prompts.

./configure is normally a non-interactive script
that accepts all its data via command-line arguments
and options. That's what this patch does.
Depend on .config.status.
Make index.html into a template (#8).

The index.html file is now gone and replaced by
a template file; it is generated by make.

This allows automatically adapting the file to HTTPS,
configuring the page title and setting a logo URL.

(Some other optimizations were made to the Makefile and
configure script.)
Move logo to img/logo.png
Updated moment and strophe
