FEATURE: plugin support for custom icons 

Plugins can now add their own SVG sprites in "plugin-name/svg-icons/".

Example: save the following as "plugin-name/svg-icons/plugin-icons.svg"

```
<?xml version="1.0" encoding="UTF-8"?>
<svg xmlns="http://www.w3.org/2000/svg" style="display: none;">
  <symbol id="testplugin-compress" viewBox="0 0 1792 1792">
    <path d="M896 960v448q0 26-19 45t-45 19-45-19l-144-144-332 332q-10 10-23 10t-23-10l-114-114q-10-10-10-23t10-23l332-332-144-144q-19-19-19-45t19-45 45-19h448q26 0 45 19t19 45zm755-672q0 13-10 23l-332 332 144 144q19 19 19 45t-19 45-45 19h-448q-26 0-45-19t-19-45v-448q0-26 19-45t45-19 45 19l144 144 332-332q10-10 23-10t23 10l114 114q10 10 10 23z"></path>
  </symbol>
</svg>
```
and then register the icon by adding this in plugin.rb
```
register_svg_icon "testplugin-compress"
```
