Nets assigned by power pins are weak, meaning they are valid
as long as there is nothing else attached to such pins. This patch
checks whether there are other wires or pins attached to a power pin
before placing a global net label.

Each named power input pin in Eagle creates an implicit connection to a
net with the name of the pin (e.g. GND, VCC). It is also done for the
units (gates in Eagle nomenclature) that have not been instantiated in
the schematics.
To emulate this behaviour in KiCad:
- Placed components are checked for power input pins, so they will have
global net labels attached to create the described implicit connections.
- As the components are placed, the remaining units of the symbol are
checked for power inputs to see if they need to be instantiated together
with global net labels.

Eagle support net labels that are naming wires not directly connected to
the labels. In KiCad it is not possible, therefore such detached net
labels need to be moved, so they touch the corresponding wire.
The initial algorithm did not take into account that a moved net label
might be placed on a wire crossing, effectively shorting two nets. This
commit improves the placement algorithm by avoiding the wire crossing
points when placing a label.

Local net labels are preceded with sheetpath (even for single sheet
schematics it is '/') causing net name conflicts between schematics and
layout. It can be easily avoided by using exclusively global net
labels, at the cost having uglier schematics.
The previous implementation relied only on the project name. When it is
set, the imported library was named '-eagle-import'. Now it tries
the project name and then the file name, using 'noname-eagle-import'
as fallback.
The library name is stored in the plugin to avoid changing the library
name after the project name has been set.
- Also makes the project and file import functions filetype dependent.
- The change from IO_MGR::KICAD to IO_MGR::KICAD_SEXP removes a conflict from a compile definition for KICAD when compiling kicad/import_project.cpp
- !! Eeschema uses Eagle plugin for loading schematics (i.e. it does not
use KiCad format anymore)
- Fixed build errors
- Fixed a few crashes
- Code formatting
