Add configs for application/x-javascript

By default the configurations from this repository ensure that `.js` files are served with the `application/javascript` media type, compressed, and with far future expires headers. However, not all users¹ use all the configurations provided by this project, or in some cases, the headers are overwritten from the level "beneath" Apache (e.g.: from `php`). Looking at the results from the HTTP Archive² from 01.09.2014: +---+--------------------+--------------------------+ | | number of requests | media type | +---+--------------------+--------------------------+ | 1 | 7406888 | image/jpeg | | 2 | 4547461 | image/png | | 3 | 4003685 | image/gif | | 4 | 3087744 | text/html | * | 5 | 2112777 | text/javascript | | 6 | 1798370 | text/css | * | 7 | 1740983 | application/x-javascript | * | 8 | 1394717 | application/javascript | | | ... | ... | +---+--------------------+--------------------------+ it's clear that the `application/javascript` media type is used less often than both `text/javascript` and `application/x-javascript`. Because of the above, the changes from this commit will ensure that Apache will serve anything labeled with the `application/x-javascript`, compressed and with far future expires headers (a previous commit³ did the same for the files labeled as `text/javascript`). - - - - - - - - - - - - - - - - - - - - - - - -- - - - - - - - - - - - ¹ #27 #41 ² https://www.igvita.com/2013/06/20/http-archive-bigquery-web-performance-answers/ Query used: select count(requestid) as number_of_requests, mimetype as media_type from [httparchive:runs.2014_09_01_requests] group by media_type order by number_of_requests desc; ³ db69327
