Subject: [PATCH] New: add week number for month view in agenda

Agenda, view by month : add a column on left side of agenda, which containt the week number for each line, so for each week. Column width at 2%, no change for width of others columns, because with 14% by defalut, so 14*7=98, the 2% for new column is available. For get date and week number, use fonctions and variables already define in file.
