bindata_assefts fails with golint

[loredo]

I needed to use this library to embed my static files but when applying golint it fails due to functions containing underscores inside names etc.
It is a little boring replacing all those functions names for my static file with CameCase style.

I finished changing your convert.go, safeFunctionName function, replacing "_" with "". to remove _ from names.

Thanks.
