Added a choice for deletion of the local bin directory, to avoid dataloss during recompilation
Version 2.22
	. Fix a bug which causes crash while indexing database.
	. Fix a bug which doesn't correctly translate lower-case nt to aa.
	. Add an option "f" to index database with full fasta headers in order to facilitate annotation.
	. Add an option to output E-value instead of log(E-value), which makes RAPSearch2 more friendly to BLAST users.
	. Adjust the format of float point values in result files to make it more clear.
	. Fix a bug that may report incorrect reference positions of an alignment given a very long reference sequence. Re-indexing database is required. (Note that alignment itself is correct but just the reported positions are off.)
