Add Tabler

[alexeygolev]

Tabler Icons seems like a good set to have available in the plugin.

Thank you for the plugin!

Thanks!

That is a really good icon set. Added.

Like in original set, you can change stroke width in Iconify components by targeting .icon-tabler in stylesheet:

.icon-tabler {
  stroke-width: 1.25;
}
