Improving translations, adding OSM with link tc conf, some err fix

[hubertgoeuropa]

PR fix some errors like:

• creating chart error(comma instad dot in decimals)
• some errors in mysql queries

@scrudden
additional comments to mysql fixes:
AvlJsonQuery.java - adding date_add to SQL, otherwise there was a syntax error for MySQL
ChartJsonBuilder.java - decimals were returned as ',' instead of '.'. Not Mysql, but this was handled.
SqlUtils.java - formatting the date for MySQL format.
schAdhByTimeData.jsp - deleting UNIX_TIMESTAMP for MySQL - there was a syntax error or no data was returned

@scrudden Sean, we will divide that PR into a couple PRs to make it easier for you to accept. We will add translations, you will migrate and then the remaining ones will follow.

Thanks.

Will this result in a Polish only string appearing somewhere?
