Update SQLite

######TL;DR;
From my test runs using SQLite:SimpleAndTabular, this decreases overall runtime ~8-15%, decreases database file size ~55-65%, and decreases SQLite functions ~35-99%.

Please review and make sure i've maintained backwards compatibility .

######Updates

First, this updates the sqlite.[h,c] from 3.6.18 -> 3.8.7.2, which improves SQLite performance ~10-30%. Next, are many code updates to SQLiteProcedures to improve SQL performance and table design.

- Removed some existing indexes since they were not being used in view queries (using EXPLAIN QUERY PLAN). This dramatically reduced the database file size.
- Consolidated ReportVariableData and ReportMeterData into ReportData to reduce data duplication
- Removed ExtendedDataIndex from ReportData and added ReportDataIndex to ReportExtendedData to reduce number of NULLs in database
- Changed createSQLiteStringTableRecord to reduce number of lookups dramatically
- Add more INTEGER PRIMARY KEYs to aid in queries
- Added views to replicate legacy tables
- Fixed errors in code adding extra data or null data to database tables
- And more...
