Pcbnew: Fix incorrect bounding box calculation of texts. Only noticeable with boards conveted from Eagle, which are using other text justification than center.
Eagle plugin: filter and replace not allowed chars in FPID(-':' and '/')  by _ or -, if they are used in Eagle footprint names (otherwise, boards converted and saved under kicad_pcb format are not readable by Pcbnew).
Fixes missing worksheet layout when there is no PCB loaded and all random brightness changes for the Cairo rendering backend.
Eeschema: fix bug loading grid size from previous session. (fixes lp:1239445)
