Remove binary build artifacts

[wieslawsoltes]

What does this implement/fix? Explain your changes.

• Remove binary build artifacts bin and obj folders and contents from Samples\RuntimeUpdates\ path.

also I have noticed some other issues related to samples/solution:

• Fixed Entities and RuntimeUpdates samples.
• Removed unused images from Libraries folder.
• Added XMLOutputTester sample to solution.
• Moved SVGViewer to Samples solution folder.
• Removed unnecessary Samples\.gitignore.
• Added solution Tests folder for test projects.

Please tell us what the following applications can be used for.

I understood this application.

Please tell us what the following applications can be used for.

• Entities
• SvgSample
• XMLOutputTester

This are existing sample apps, I have just added them to solution and fixed build. If they are not helpful I propose to remove them from repo.

[mrbean-bremen]

These are examples applications, and I agree that they are more visible if added to the solution. I haven't checked the usability of the examples per se - I agree with @wieslawsoltes that they shall be removed if they are obsolete.

• Entities
• SvgSample

These are just sample codes.
Running it will raise an exception.
Because it is a CLI, you may need to specify arguments.

• XMLOutputTester

This could be used for code-based testing if modified.

I think that it is better to write description of projects in readme or wiki, if add them to solution.

[mrbean-bremen]

A description of the samples on a separate documentation page is a good idea! Maybe I will have a look later...

[mrbean-bremen]

I checked the samples. Both are command line tools, but don't need a special command line argument (an example image is provided in both cases).
SvgSample reads an SVG file, changes the style of one of it's elements, and saves it to a png. This works for me.
Entities is supposed to read a file with some unknown entities, providing these entities as a dictionary. This fails, which seems to be a bug - the functionality is probably broken - I'll add an issue for this (added #651).

I still think it is a good idea to have the samples in the solution to improve their visibility.
Concerning the documentation for the samples - I may get at this some time later (currently not up to it, caught a cold), or someone else could have a go.
