Merge slog-bloat admin into slog - leaving slog-bloat with the historical gumph

[bobbingwide]

While filtering daily trace summary files to create files to drive the performance analysis routines on a remote server I find myself toggling between slog and slog-bloat. Sometimes I want to see the request types in the ( downloaded ) daily trace summary file.
It would be nice if the charts/reports in slog were easily accessible from slog-bloat.

Requirement

• Ability to run slog reports against filtered / downloaded files
• Make slog and slog bloat easier to use
• Reduce complexity

Current position

• Both slog and slog bloat are dependent upon oik-bwtrace and sb-chart-block.
• Both use shared library functions
• slog's admin was written as procedural code
• slog-bloat's admin is better structured
• slog-bloat is dependent upon slog
• slog-bloat relies on slog's oik_autocode logic - is this true?

Proposed solution

• [x] Extend slog's file list to include files in slog-bloat's downloaded directory ( slog_bloat_options[_slog_downloads_dir] )
• [ ] Cater for the Download directory not being specified, or blank.

I've decided this is a sensible idea.

The final outcome being that:

• slog will do the charting stuff
• either slog-bloat will contain the oik-batch vt-driver.php logic or it's merged into slog.
• slog-bloat will retain the historical results.

Steps to achieving this:

• [x] Refactor the slog report logic to be object oriented as a Reports tab under slog-bloat.
• [x] Rework the settings logic so that the options are only updated on the Settings tab.
• [x] Remove slog-bloat's dependency on slog.
• [ ] When the refactoring is complete copy slog-bloat logic to slog.
• [ ] Eliminate admin logic from slog-bloat

The current position is that slog-bloat has 5 tabs on the admin page. I need to copy this logic to slog and rework it:

1. Change slog-bloat to slog
2. Change slog_bloat to slog
3. Rename some files.

slog should then work the same as slog-bloat.

In the very few sites that have slog_options and slog_bloat_options in the wp_options table, these may need to be deleted.
