Collect better statistics on items

[takkaria]

Roll however many thousand levels and look at the items in them.

For combat gear, it would be put into the categories {good} {excellent} {artifact} etc.
For consumables, it would be good to have it itemised with how many there are per level (including stack sizes)

See also #342 and #776

Those are other "collect stats" tickets. For other tickets specific to item balance, see also #192 and #720.

fizzix and myshkin have both written generators for this. It's now merely an issue of how and where to integrate them into the codebase, document them etc. Once they're somewhere in ​http://github.com/angband/angband this ticket can be closed. That might enable closing #776, #192 and #720 as well.

note that fizzix's branch has had angband.exe added once and taken away again-- we'll have to cherrypick

Reopened for the collation of stats over multiple runs of -mstats and output to nice parseable format (sqlite?). I don't know how to do four-dimensional tables in sqlite (or indeed anything else), but what we need is the contents of

struct level[100] {
    int kinds[z_info->k_max][ORIGIN_MAX]; 
    int egos[z_info->k_max][z_info->e_max][ORIGIN_MAX]; 
    int arts[z_info->a_max][ORIGIN_MAX];
    int flags[z_info->k_max][OF_MAX][PVAL_MAX];
    int races[z_info->r_max]; 
    int vaults[z_info->v_max];
    int pits[z_info->pit_max];
};

summed over all the runs.

Punting in accordance with new milestone policy (that any other milestone is only set once someone is actually working on the ticket).

It would be handy to add int feeling[10][10]; to the structure, so see whether level feelings are fixed.

[magnate]

This is finally done: running angband with -mstats produces an sqlite db which you can interrogate with phpliteadmin (both myshkin and magnate have this set up on their web servers). Obviously there will be continuous improvement, but this can be closed.
