Improved Czech translation

[Jujan]

A lot of strings were reworked to better fit situation.
The rework is not complete.
I need screenshots of the strings in app to examine the situation and make proper changes.
The strings I need to see are on lines 13, 14, 15, 16, 18, 19 and 24.

Hi,

Julian, thank you very much for your contribution.

@semack Nice to hear. I will mark this pull request as ready as soon as I translate the rest of strings. Would you help me out?
I need to see in which situations these strings on lines 13, 14, 15, 16, 18, 19 and 24 appear in app on device. I need screenshots as I have no idea how to reproduce these lines.

[semack]

It wont help, cuz different devices have different screen sizes.

[Jujan]

@semack We might be in miscommunication here. When does string on line 13 appears? What is the trigger event?

[semack]

You always can check the sources. If you mean `"load_failed_retry": "Load failed, tap to retry..."', it will appear on communication problems in the search grid. It will appear at bottom of it.

[semack]

14 - is similar to Not Available. N/A
15 - if no compatible tape files found on the player screen
16 - title on app bar when selecting the local file from storage
18 - retry button if communication problems on any request too remote source
19 - error message when the problem of retrieving the tape file from remote.

@semack Exactly what I need. Thanks. I am no programmer. :) Making changes accordingly. Where is the "Not Available" to be seen? What about 24?

[semack]

24 - Notification after the long press on the selected file if you wish to download it to the storage.

[semack]

Not Available, please leave it as "-"

[Jujan]

Okay. Thanks for your cooperation on this topic. Final version of translation is complete. The pull request is ready to go.
