v1.4.1: Two new command line options

Two new command line options! -a and -n:

* -a, --all-results makes the program print all search results found for a word

* -n, --number-of-results=INTEGER prints the first INTEGER search results

Also expanded the help string.

Changes:

* The program is now exception safe from figlet errors (invalid font file syntax, style not supported etc.)
* New --dumpversion option, useful for scripts.

Add a check for --emoji-style option

The argument passed to the -e (--emoji-style) option is now checked to verify if it is valid, if not the program exits with an error.

Add a custom emoji/symbol option

Added an option which lets the user use the symbols of their choice to denote the like/dislike count and ratio.
Also documented this feature in help.cpp

Add emoji customization and some build changes

Users can now customize the style of the emojis used to represent the like and dislike count (and ratio) by using the -e (--emoji-style) option. Try it out!
Also, the figlet font directory is now customizable at build-time, which improves compatibility on systems with non-conventional directory structures like Termux on Android
Also add some new fonts

Add comments, edit error output format

The error output format now resembles the default getopt error style (program-name: error) and network-related errors resemble curl errors - program-name: (error-code) error

Add command line options and custom figlet font support

The program now supports command line options (3 for now) and can use custom figlet fonts (yay). Run "urbanite --help" for more info ;)

Distribute source code into various source files

Distributed the source code into various source files to speed up compiling with make. Also updated and improved Makefile drastically.

Modify directory structure, minor changes to Makefile

Added Makefile, minor code improvements and changes in outptut format
