add "ratio" as filter- and search-option

[chqp]

While height and width of videos can already be used to filter and search for videos, their easily calculable dependents "aspect ratio" and "orientation" would likely give the apps value for users a significant boost in relation to the necessary effort to implement them.

value boost:

• hypothesis 1: media player users have always HATED those annoying black bars appearing on the screen whenever a landscape oriented video was followed by a portrait oriented video and vice verca. At least latently - but for sure globally and from the beginning of time.

• hypothesis 2: users would LOVE being able to filter/select videos of matching aspect ratios and orientation. With that, they could easily create playlists of videos perfectly fitting into the same canvas. =No more black bars

effort:

• since height and width as basis for their calculation are already there and ready to be used, it would simply need a new variable "ratio" which could be calculated and defined easily whenever width and height were just set for a video file added or updated. =Literally just a small step of coding of a one-step calculation for a dev - but a somewhat giant leap for mediachips users among mankind... (width/height=ratio)

for reference:
XnViewMP introduced exactly that for filtering and sorting pictures;

bonus:
ratio would enable many use cases; ie to distinguish between landscape oriented, portrait oriented and cubic videos. Even more intuitive would be adding another variable "orientation" or to replace the displayed values with their commonly known labels; ie. show 4:3 instead of the value 0,75 and 16:9 rather than 0,56 accordingly
