Moves bits.rb to lib dir, deletes has_kspawn.rb
Implements first few line parsers for mobile

Vnum, Name, Short desc, Long desc, Description all have parsers.

Also method for expecting lines changes. Instead of indexing an array
of symbols and incrementing the index each time a line is parsed, just
set a variable to a symbol and reset it to the correct next line type
after each line is parsed. Why? Some parsable elements are on the same
line, so iterating over LINES (misnomer; it really contains attributes)
would be difficult.
