Updated org.apache.httpcomponents:httpclient to 4.3.5.

This was required because of the following CVE: http://mail-archives.apache.org/mod_mbox/www-announce/201408.mbox/CVE-2014-3577. For additional information you can also check out https://bugzilla.redhat.com/show_bug.cgi?id=1129074.

Since there is no corresponding `httpcore` with this version, the 2 artifacts had to be split up, considering that:
```
 org.apache.httpcomponents:httpclient:jar:4.3.5:compile
 +- org.apache.httpcomponents:httpcore:jar:4.3.2:compile
```
