Fix missing FontAwesome special characters

[csidirop]

Fixes #6

The current implementation does not load the arrow icons correctly, as you can see here:

According to these instructions, the CSS styling must be corrected. With those corrections the icons are shown again:

There is another occurrence wich calls "FontAwesome":

AvantSearch/views/public/css/avantsearch.css

Lines 497 to 500 in e767b90

	.search-selector-button:after {
	content: "\f0d7";
	font-family: "FontAwesome";
	padding-left: 6px;

Which I left because I didn't know what it affected. But I can deliver that later if wanted.

Hi @gsoules hope you are well. Are you still working on this plugin?

[gsoules]

I am not actively working on the plugin, but thank you for bringing this to my attention. I'm not seeing the issue on any of my sites. I'm wondering why the CSS behaves badly on some installations, but not others. Do you know?

To be honest I don't really know (anymore).
It seams that there is free and paid version. But I can't remember where the fonts where coming from. Omeka installation? If so they ship now with newer versions but still have the old ones (v 4.7).

I can look into it as soon I have some spare time.
