[feature/template-engine] Deleted $template from phpbb_template_compile class.

Browse Source 
phpbb_template_compile is now much simpler. It takes complete file paths
as inputs, either source template path or source template path and output
compiled template path. The number of methods also went down to two -
compile template and returned compiled text or compile and write to file.

phpbb_compile class is responsible for determining source and compiled
paths. It already had all the data necessary for this, now the code is
in the same place as the data it uses.

Preserve whitespace.
PHP removes a newline after the closing tag (if it's there). This is by design.
Consider the following template:
<!-- IF condition -->
some content
<!-- ENDIF -->
If we were to simply preserve all whitespace, we could simply replace all "?>" tags
with "?>\n".
Doing that, would add additional newlines to the compiled tempalte in place of the
IF and ENDIF statements. These newlines are unwanted (and one is conditional).
The IF and ENDIF are usually on their own line for ease of reading.
This replacement preserves newlines only for statements that aren't the only statement on a line.
It will NOT preserve newlines at the end of statements in the above examle.
It will preserve newlines in situations like:
<!-- IF condition -->inline content<!-- ENDIF -->
