Title: Pass pacakge names internally as symbols

The function "el-get-as-symbol" is only used in interactive functions
that accept user input. All other functions assume packages are passed
and returned as symbols.

Assertions have been added to many functions that take packages or
lists of packages to enforce this. These can be removed later once we are sure that we're not passing any strings internally.
