RFS and Upload: librecad

[Innocent De Marchi <tangram.peces@gmail.com>]

Hello everyone,

I have updated the librecad package to version 2.1.3 [0].
The package is lintian clean and it does not have important news
regarding the last update.

Please, upload it to the repository.

Regards!

I. De Marchi
