Arabic translation for the UI interface, however arabic language is a right to left language, so for proper display (especially when text contain both Arabic and English text) it is required to add dir="rtl" in the style, i suggest adding a checkbox in setting to trigger this for right to left languages

rework filename pattern function go through the pattern once and not calculate any of replacements until they are actually encountered in the pattern.

the file_decoration passed into apply_filename_pattern() is formatted to lowercase to increase compatibility
the use of case sensitive srt.replace()

but because the newly implemented "time format" is case sensitive
the lowercasing the file_decoration will cause time format to be broken

in order to resolve this issue
I decided to replace every srt.replace() and in if "str" in x to regular expression (case insensitive) equivalent

format:
[datetime]
[datetime<Format>]
[datetime<Format><Time Zone>]

into "if forced_filename is None:"
no need to initialize it if it's not going to be used

remove loading .js files from scripts dir (they go into javascript)
load scripts after models, for scripts that depend on loaded models

Move out images browser from project

I don't feel this being efficient

Statistics logging has changed to {filename : list[losses]}, so it has to use loss_info[key].pop()

Updated translation for everything except the Settings tab
