Less: Small fixes & improvements (box-shadow & font)

[Ninos]

Fix: box-shadow

You should use ~"" instead of just "", otherwise you get following result after comiling: box-shadow: "" 0 1px 2px rgba( 0, 0, 0, 0.2 );

Improvement: Added possibility to disable the font-face

So it's possible to use custom font icons without loading the flexslider font icons (for better performance / less files to load on client side)

Here's an example with FontAwesome:

@font:                           false;
@font-name:                      "FontAwesome";
@flex-direction-nav-icon-prev:   "\f053";
@flex-direction-nav-icon-next:   "\f054";
@flex-pauseplay-icon-play:       "\f04b";
@flex-pauseplay-icon-pause:      "\f04c";

Hey there, what's about this PR? These are only small fixes and simple improvements. Without this fix you cannot compile from .less e.g. with less.php... :-)

Ref: #1277

@jeffikus what's about following PR? :))

[jeffikus]

@Ninos thanks but just no time to add to 2.6.0 release, have assigned to 2.7.0 though!

[Ninos]

Ok thank you!

[Ninos]

Hey there, this PR is still not merged, any news about that? These are small but significant improvements for theme developers which not want to load an additional font.

@Ninos when i get time to tackle this I will, but at the moment there are more pressing issues that i need to deal with.

[Ninos]

Hey @jeffikus I'm sure you have no much time, but after version changes I always need to implement my small PRs into project libraries. These PRs are very small, if you have no time, you can add me as project dev, after that I'll merge there PRs.

Another very small issue #1492

Check and merge of both PRs should be done in less than 10min

@Ninos thanks, I have some time this week (finally) - will take a look at this first :)

[Ninos]

Thank you @jeffikus :-)

BTW: @font-path should also be changed to @font-path: "../fonts"; I've already deleted my branch, so I cannot add changes to this PR :/
