Segment names are Unreadable in ErgFileOverview

[ericchristoffersen]

Currently segment names stomp each other in overview.

Mostly I care because 95% of my virtual rides have a bunch of named segments.Two parts to fix:

First is to add an 'end' field to the ergfilelap. For non-segment laps this has no meaning and is kept as a negative number (-1). This allows overview to know a segment's start and end.

Second part of fix is to distribute segments to rows in overview so they dont stomp each other.

Hopefully someone in the future will feel inspired to replace the ascii art in overview plot with something colored and graphical that takes into account the size of printed text. Knowing text size would allow named laps to be distributed to rows and so also be printed without their names stomping over each other.
