[ADD] web: add parse monetary method

In field_utils, the parse monetary method was remapped to parsefloat. In this commit, we add a specific parseMonetary method to handle currency specific formatting.

+ * Parse a String containing currency symbol and returns amount

+ * @param {string} value 
+ *                The string to be parsed

+ *        a description of the field (returned by fields_get for example).
+ * @param {Object} [options] additional options.
+ * @param {Object} [options.currency] - the description of the currency to use
+ * @param {integer} [options.currency_id]
+ *        the id of the 'res.currency' to use (ignored if options.currency)
+ * @param {string} [options.currency_field]
+ *        the name of the field whose value is the currency id
+ *        (ignore if options.currency or options.currency_id)
+ *        Note: if not given it will default to the field currency_field value
+ *        or to 'currency_id'.
+ * @param {Object} [options.data]
+ *        a mapping of field name to field value, required with
+ *        options.currency_field
+ *
+ * @returns {float} the float value contained in the string representation
+ * @throws {Error} if no float is found or if parameter does not respect monetary condition
