Change subscription numbering pattern and frequencies

Serials numbering pattern and frequencies are no more hard-coded. Now
it's possible to create, edit and delete numbering patterns (and
frequencies). This implies new sql tables (subscription_numberpatterns
and subscription_frequencies)

Numbering patterns behave almost as before, there are still the same
values to configure (addX, everyX, settoX, whenmorethanX). lastvalueX
and innerloopX remain in subscription tables.

There is a new value in numbering patterns: numberingX. For each
"column" (X, Y or Z) you can tell how to format the number. Actually
numberingX can be set to:
 - 'dayname' (name of the day) (0-6 or 1-7 depending on which day is the
   first of the week)
 - 'monthname' (name of the month) (0-11)
 - 'season' (name of the season) (0-3) (0 is Spring)

These names are localized by using POSIX::setlocale and POSIX::strftime
and setting a 'locale' value to the subscription. Locale have to be
installed on the system.

Frequencies can be configured using 3 parameters:
 - 'unit': one of 'day', 'week', 'month', 'year'
 - 'issuesperunit': integer >= 1, the number of received issues per
   'unit'
 - 'unitsperissue': integer >= 1, the number of 'unit' between two
   issues
One of 'issuesperunit' and 'unitsperissue' must be equal to 1.
Examples:
  unit = 'day', issuesperunit=3, unitsperissue=1 => 3 issues per day
  unit = 'week', issuesperunit=1, unitsperissue=3 => 1 issue each 3
  weeks

Prediction pattern is now computed server-side and is more consistent
with what Koha will do. The publication date is displayed alongside the
serial number.
Irregularities can now be checked one by one, in the prediction pattern
table, or if frequency is 'day-based' (unit is 'day'), there is the
possibility to check all issues for a week day at once.

When an irregularity is found, there is the possibility to keep the
serial number unchanged, or to skip it. It is configured at subscription
creation or modification.
For instance, with a daily subscription you can have:
  skip serial number  |  keep serial number
----------------------+----------------------
 2012-01-01  ¦  No 1  | 2012-01-01  ¦  No 1
 2012-01-03  ¦  No 3  | 2012-01-03  ¦  No 2

To lighten the subscription modification page, manual history has been
moved in its own page subscription-history.pl which is accessible on
subscription-detail.pl, tab 'Planning'.

Important note: updatedatabase.pl script takes into account existing
subscriptions and create a numbering pattern for each one. Frequency is
mapped to the correct entry in subscription_frequencies table
