Seq now uses []int for Scores
seqfilter now agrees with []int representation of Seq.Scores
added sequtil.QualStringToIntSlice
store.go now copes with []int representation of Seq.Scores, subject to revision though
fastaqual can now handle []int representation of Seq.Scores
added StringToPhredScoreSlice to sequtil, now maybe fastq can play nice
FastqReader now returns Seqs with []int Scores
