About the 1st milestone: implementing default conky functionality

[npyl]

The 1st milestone is all about implementing the required functionality for showing the default conky config!

Some things have already been implemented and are thus omitted!

This requires implementing following:

• [x] update_meminfo() #6

• [ ] update_running_processes() #8

• [x] get_top_info() #10

• [x] get_freq() #11

• [x] update_cpu_usage() #13

• [x] update_net_stats() #14

• [x] Implement Semaphore Class #2

NOTE: update_meminfo() has been implemented but because I am using some apple code I can't tick it yet, unless I modify the code in order to comply with the restrictions of the license

This problem has been amended.
