modified analysis_job table : replaced input_id varchar(100) with

input_analysis_data_id int(10) which joins to analysis_data table.
added output_analysis_data_id int(10) for storing output_id
External analysis_data.data is LongText which will allow much longer
parameter sets to be passed around than was previously possible.
AnalysisData will also allow processes to manually store 'other' data and
pass it around via ID reference now.
