Mainly http-related fixes et. al.

http/index.html:

*) minor typo fix -- taking out a stray newline char addition to the form.append() call...  which is irrelevant really;

*) refactoing exclusion of rows from dataset to a more flexible (yet temporary) CLI (textual command-line-interface) form;

*) adding a column display feature to the dataset;

possible bug-fix (refactoring really) -- allowing display of single-row datasets... not really important as single-row stacked datasets arent applicable anyways (unless used for some testing/debugging)...

*) bug-fix -- during addition of a new job, if supplied-args contain error the button for submission-to-server was disabled and stayed disabled thereby not allowing any re-submission without refreshing of the whole page.

censoc/spreadsheet/csv.h (via dataset_1/cortroller.h) -- bug-fix: overzealous assertion. Discovered via relpacement code (since migration to gcc 4.7.2) which sets the istream object from vector for csv parser; yet the replacement code does not implement 'seekoff' and 'seekpos' (needed for 'tellg' to work properly) and this in turn breaks assertions in csv.h relying on tellg returning valid values (the non-assertion code does not rely on 'tellg' at this stage).

http/server.cc -- given that, currently, uncormpressed data is being passed from web-client to http-server, have refactored the code allowing web-client to send more-than previous limit (increase from 32 to 64 meg).
