Fix paths for the online documentation assets

If we ever need to make nested pages, paths will be
a bit of a problem. Perhaps there is a way to convert
relative paths into absolute while parsing Markdown.

For now, just changing all paths to relative should be
fine.

 On the right side of the arrangement view is a panel where you will immediately find one blue rectangle with a number and perhaps some dots. Below it, at the bottom of the panel, is the `ADD NEW` button. This is the pattern dock, a list of all patterns that you currently have made for your song. Clicking on the button will, predictably, add a new pattern, and once there are too many of them, buttons for scrolling the list will appear. You can also scroll with your <kbd>Mouse Wheel</kbd>.

 Just like notes in patterns conform to a metronome, ticking away at regular intervals, the entire song conforms to the same metronome as well. The arrangement grid in front of you represents the chronological order of patterns in your song, with each column corresponding to a pattern-sized unit of time called _a bar_. Bars are further split into 8 rows, called channels or tracks. This gives you the means to play up to 8 unique patterns at the same time.
 
-_Bosca Ceoil Blue_ automatically keeps track of every bar that you fill with patterns, and when the time comes to [export your song](/export_import.html), everything that you've added up to that moment will be included. Keep in mind, that the maximum length of any song is 1000 bars.

 To add a pattern to the arrangement, drag and drop it from the pattern dock, or <kbd>Left Click</kbd> and drag one of the existing patterns on the grid onto another cell, making a copy. Hold <kbd>Alt</kbd> as you do this, and instead of a copy a new variant of the original pattern will be created. You can also simply <kbd>Alt + Left Click</kbd> on a pattern to turn it into a variant.
 
 <kbd>Right Click</kbd> removes the clicked pattern from the grid. This doesn't delete the pattern, however, and you can still use it later.

 Separate from other effects is _swing_. Using _swing_ you can adjust the timing of the played notes. Normally, a note in _Bosca Ceoil Blue_ can be played at every tick of the metronome. The swing effect takes two consecutive notes in a pattern and adjusts their proportions, such that one of the notes takes the majority of their combined time and the other takes the minority.

 In other words, if two notes take _two ticks_ to play, then adjusting the swing effect to the left makes the first note take the smaller portion of those two ticks, and the second note — to take the larger portion. Moving the slider to the right does the opposite, and the first note takes the larger portion.
