Support for ANSI color code

[Pixelbo]

Hey, je suis français mais puisque tout ce github parle anglais, i'm going to speak the king's.

First of all, I don't have a great knowledge in Vue.js at all, I've made this modification for my robotics team at INSA Rennes. (all help is appreciated 👈(ﾟヮﾟ👈) )

I've added support to ANSI color coding (at least tried) to log messages, charts title and single values (text).

I made small modification of ansi_up code which convert ANSI coloring into HTML div with style (foreground et background text).

In DataSeries.js and Telemetry.js, I added a colored_name member which contain the HTML colored text, the name member still have the ANSI code with the text in it.

Because ANSI code have semi-colons in it, I've had to modify serverMessageReading.js to allow semi-colons in the text if and only if the telemetry is a text.

Vue.js double mustache {{serie.name}} parse the variable inside of it as text but we have the text inside a div, so I used v-html to counter this restriction (see vue docs).

I know there can still be some problems somewhere, I look forward to fix them!
