Enhancements + Fixes (#41)

* Signal does seem good after all.

* Add alias `here` which shows details of everything in the current location.

* Move instant messengers to consistently be at the end of the favorites bar.

* Change to single quotes so that the pwd is per-call instead of per-source.

* Specify the video codec so that the command works on openSUSE.

* Refactor so that there is a shared/common fact list.

* Add ffmpeg as a package variable.

* Reformat long comment.

* New file for installing package manager apps for workstations.

* Call the workstation package manager tasks.

* Change to parenthesis to look better.

* Explicitly add a video flag, add recursive searching, fix a bug with -f ignoring input.

* Add ability to "force" the compression, deletes old files and regenerates them. Input is now passed with i rather than f for file/folder. f is now used for force.

* Fix skipping the file if it's already compressed. Enhance readability of log text.

 		Reduce the filesize of a video file to make it stream well. It also
 		  helps with the file size for placing the file into a backup system.
+		  Currently only set up for libopenh264 and mp4 files.
 		
 		Parameters:
-		  -f input : The input file or folder with which to search for video files. 
+		  -i input : The input file or folder with which to search for video files. 
 		             If nothing is provided, current directory (.) is assumed.
 		  -v bitrate : The video bitrate to convert to, defaults to 2000k.
 		  -a bitrate : The audio bitrate to convert to, defaults to 128k.
+		  -r : Recurse the entire directory structure, compressing all video files.
+		  -f : Force recompressing any files by deleting it if it already exists.
 		  -h : Display this help messaging.
