Increase size of mysql field in export table for column with CRM_Utils_Type::T_INT type

Overview

Increase size of mysql field in export table for column with CRM_Utils_Type::T_INT type.

Example use-case

1. Change label of phone type "Mobile" to "Telefon komórkowy" (which is Polish translation with 18 length)
2. Search for contacts with this phone type
3. Make an action "Export contacts"

Current behaviour

Current size is VARCHAR(16). The db error occurs:

[nativecode=1406 ** Data too long for column 'phone_type_id' at row 1]

Proposed behaviour

Increasing size to VARCHAR(64) allows exporting works fine with option labels longer than 16 chars. Not only built-in dictionaries like phone types but also for custom options/custom fields.

Comments

To be more precise I should increase the length to VARCHAR(512) because of civicrm_option_value.label definition.
