scss cleanup, performance tuneup

scss cleanup
---removed bootstrap (v3.1 original w/ solution template)
---bootstrap-sass-official is now the only bootstrap lib in vendor/bower
---site.css is the only compiled css
---fixed scss compilation issue causing mis-styled login form in nav
---removed glyphicon as font in lieu of font-awesome
performance tuneup
---restricted search result sets to exclude unnecessary and unfilterable fields
---adoptee search response size/latency reduced: 8mb/8s (before); 1.3mb/1.5s (after)
---adopter search response size/latency reduced: 14.6mb/23s (before); 185kb/<1s (after)
---may be able to close issue #90 without further adjustments
note: adopter "before" numbers skewed by the fact that matched adoptees had for some reason been added to search result set, removing this alone reduced significantly
