Sprockets 4 does not support regex in precompile assets configuration

[Yanchek99]

Sprockets 4 has introduced breaking changes when using a regex in the precompile assets configuration. Instead the fix is to pull those assets in using the manifest.js configuration. Details

The following line causes issues when using Sprockets 4.

fontello_rails_converter/lib/fontello_rails_converter/railtie.rb

Line 7 in c781f95

app.config.assets.precompile << /\.(?:svg|eot|woff|woff2|ttf)$/

FontAwesome has a fix that still uses the precompile path however they know the names of the font files as where we do not. FortAwesome/font-awesome-sass@b8dd32c
